DIGITAL SERVO BLOCK PRODUCT SUMMARY AND FEATURE The servo block in chip uses the input signal processed in the RF amplifier and read from the CD-DA/VIDEOCD/DVDP Disc. The digital servo block receives the input signal for focus and tracking. OPERATION DESCRIPTION NORMAL PLAY HOME IN Summary If a PS signal is not produced after a specified time after moving the P/U from its initial position to the innermost track using the reverse sled move, it assumes that the P/U has homed in and moves forward for the amount of time it takes for the P/U to escape the lead in area. Then it finishes the task. input signal : PS0, PS1 output signal : SLD operation MODE selection : ( LIM = HDWcmd's factor ) LIM = L Sled stop determined by the limit S/W LIM = H Sled stop determined by the position sensor
COMMAND SLDcmd(A4xxxx cmd) Transmission Related REGISTER REGISTER SKCKd FGstp tHFwd Operation Description Sled is moved in the reverse direction. If PS1 or PS0 shows no signal change for a set length of time (FGstp), forward KICK the sled output for tHFwd, then return to Vref.

Home In detection by limit S/W (when there is no sled position sensor) : If there is a limit S/W, it is set to HDWcmd's LIM = L (sled stop determined by limit S/W), DSSP's PS0 pin is changed to SSTOP, and the limit S/W is connected to that block. SLDcmd's home = L (normal), SMOV, SPLY's bit is controlled, and MICOM is manual.
FOCUS SEARCH (DISC DETECTION)
Summary : The FOD outputs delta waves and moves the actuator up and down to determine disc presence and disc type using the FE (S_CURVE) signal. The results are sent to MICOM using a data bus.

Operation Description When the focus search command is received, the output signal FOD starts at the Vref voltage and outputs triangular waveforms. At this time, search speed or slope is decided by the FSP value from the disc detect command coefficients. Disc presence and type are detected by the disc detect command, and its references include the following: (1) FEpk : FE input signal's peak to peak value (2) DBL : Number of S-curves (3) POS : S-curve detection location (4) DIN : S-curve presence The location for carrying out disc detection is in the middle of moving from the lower value to the upper value when AUTO = L and UPDN = H. The results are stored in [FEpk] and [DDTdt]. After completing the disc detect command, the OR values of the two memories are output to MICOM (refer to command set's DDTcmd).

When FSOS = "L", S-curve is detected in both directions without regard to DDTcmd's UPDN bit. When it is "H", S-curve is detected when UPDN = "L"(actuator up) and actuator is down. When UPDN = "H"(actuator down), S-curve is detected when actuator is up. This is because the actuator and the system can be initially unstable, and the S-curve must be detected when they are stable. Also, you can decide on a full search or half search during DDT using FSHF, to choose the search time. DDT detection waveform

Operation Description The input gain's automatic adjustment has the ability to absorb the deviation of the focus and tracking error's signal level from the RF IC for each set. Also, when there is no gain swiching feature for different disc types within the RF IC, it corrects the focus and tracking error's signal level difference. For focus, the s_curve size measured during focus search is used as the input gain amp's input. For tracking, the TE's track zero cross size when the disc is spinning in off track status is used as the input gain amp's input. Automatic adjustment is carried out so that it is near 4.2V (6ch) no matter what the input gain amp's output level is. The look-up table given above shows the input gain amp's gain characteristics. This has the advantage of using the ADC's input range to its fullest, and improving the decomposition ability in quantization. If you have a gain feature in the RF IC according to disc type and the automatic adjustment feature is used for the total loop gain, the input gain can be set to a fixed value at an appropriate level by manual setting.

PIT DEPTH CONTROL (RESERVED). Summary When finding tracking error in the DVD using the DPD (Differential Phase Detect) method, the TE signal's size and offset can differ according to the various pit depths for each disc. To compensate for this characteristic, a delay of the opposite polarity to the RF Amp's (A, B) and (C, D) is given, and the amount of delay in the servo is adjusted to have a TE of a regular size regardless of the lens location. input signal : TE output signal : TRD, DPC

Operation Description The TE signal's amplitude and median changes according to the lens shift amount, due to the influence of the disc pit depth. The deviation is the most severe when the inner/outer shift amount is at its peak. Therefore, if you vary the RF IC's depth delay and carry out automatic adjustment, the TE signal's amplitude and median will be regular regardless of shift amount. This algorithm uses a method where the inner and outer circumferences' medians are the same at the maximum shift.

Operation Description Out of the TE(tzc) signals, the TEmin and TEmax are measured in the periods that pass through Vref and satisfy all the conditions of fmin and fmax. The median of these two values is calculated, and if these periods are continued for the number of nTbals, the difference between the average value of the medians and the adjustment reference level (= Tofst) is said to be the balance error. If the error is smaller than TBok, the adjustment is ended, but if it is larger, the product of Tbal's previous value and TBk is output. When you renew the Tbal output value, the gain or delay within the RF's TE AMP varies, making the TE signal's balance error change as well. A wait time (TBwt) longer than the settling time according to such analog characteristics is set. When the system is stabilized after the wait time, the operations for balance error detection are repeated.

FOCUS BIAS CONTROL Summary Focus bias adjustment is carried out so that playback is executed when the RF signal quality is at its best. The quality of the RF signal is shown by the jitter amount, but it is difficult to have an algorithm that can measure jitter on the IC and find the minimum point. Therefore, you use the characteristic where the jitter is always at its minimum near the focus bias point with the largest RF envelope size. The focus bias is adjusted so that the envelope is at its maximum size.

Operation Description TRACKING KICK/BRK output : The track kick pulse is the TRD output average value (TRD_avrg) before jump, overlapped with the kick level (TKCKd). The track kick pulse reverts to brake when the track counter (H.CT) becomes larger than the jump z trk # (N)*TKj_k, and the level is TKCKd*2*TKl_k. Maximum Kick Time Limit : If the MIRR period within the kick area becomes larger than ivbuf (Jstp) + Kwdt (according to BTS select conditions), it is a long-term error of the MIRR, and there is a change to brake for safety. SLED KICK/BRAKE output : When the jump trk # generated by the track kick reaches the sled movement count (SMcnt), the sled output average value before the jump (SL_avrg) and the sled move level (SMlvl) kick are overlapped. Sled reverts to brake along with the trk kick's reversion to brake, and the level is SMlvl*2*SMl_k.

Operation Description Position Sensor and track count method : When the multiple N-S magnetic poles attached along the sled deceleration gear's cylinder starts to rotate by sled motor operation, the 2 hall sensors with the 90 phase angle detects the magnetic change and outputs a voltage in sine wave form. Also, this signal is changed into a logic signal in the comparator, and is input to the DSSP's status input as PS0 and PS1. The tolerance for the phase angle 90 is decided by the mechanical location, and if it is accurate, 4 FG edges are made in the PS0 and PS1's 1cycle. The number of trks per FG pulse can be calculated by deck mechanisms such as the number of magnetic poles, etc. The value can be stored in the ENTc register by MICOM. When the FG edge is detected according to sled move, the S/W counter (STcnt) increases by ENTc, and you can measure the number of trks moved even without H.CT operation.

SLED KICK/BRAKE Output : (1) Waveform : The sled kick pulse is the SLD output average value before the move (SL_avrg), overlapped with the sled kick level (SKCKd) and output to SLD. The sled kick pulse reverts to brake when the STcnt becomes the reverse count value found by move trk number (N)*SL_k. At this time, the brake level is the same as the kick level (SKCKd), but while the kick's point of reference is SL_avrg, that of brake is Vref. This is because the average output level before and after a move is different for long-distance moves. There isn't that much change in the lens shift in short movements in the level of track jump, so the kick/brake and stabilization area's output reference level are both SL_avrg (TRD_avrg). But in long-distance moves, the lens is at the midpoint, so there is no more meaning for the output average after kick. Therefore, the TRD output during sled kick/brake and stabilization area are held at Vref instead of TRD_avg, and off status is maintained. (2) Limit function for emergencies during KICK/BRAKE : Unlike track jump using MIRR/TZC, PS0 and PS1 have almost no chance of an output error due to circuitry reasons, apart from the damage of the hall sensor or comparator. However, there is a chance of kick time becoming very long, or getting trapped in an endless kick when the load on the sled becomes abnormally large. To prevent this, there is an emergency detection timer (PSstp) that stops the move and changes to pull-in mode when the PS edge doesn't come out within a specific length of time.

MOVE end and stable period: (1) BRAKE end : In the deceleration area, if the interval between the FG pulse period is longer than the time set by MICOM (FGjsp), or the movement direction is incorrect, the SLD output is set back to Vref and the brake is stopped. (2) Stabilization area : The SLD output is held to Vref for the stabilization area set by MICOM. TRD also maintains Vref status. When the stabilization area comes to an end, it diverges into the TrSV routine within the Fon_int, and attempts normal tracking/sled pull-in.
SPEED CONTROL TRACK JUMP & SLED MOVE SPEED CONTROL TRACK JUMP Summary Speed control track jump is a track jump method that moves the P/U's lens. The number of tracks to be jumped can be set between 1 and 255. The speed control kick detects the P/U lens'speed in relation to the disc using the track error and MIRR signals from the disc, and controls the TRD kick signal so that it matches the DSP speed profile. You can select the TM_win to reduce TZC errors such as glitches generated by initial kicks. When tracking is on, lens brake and loop gain up periods can be selected. INITIALIZE When INIcmd's TKJM is set to H and JPMcmd is received, speed control track jump is carried out for the number of tracks set by command. Other initial conditions are the same as those described in track jump using kick/brake.

MIRR/TZC SPEED CONTROL SLED MOVE 1 SUMMARY This method is a speed control sled move, but it uses the TZC/MIRR in the detection signal, consequently using the tracking drive (TRD) as well as the sled drive (SLD) as control output. It also has the track kick correct for eccentricity. However, it needs enough tuning because the combination of the mixing is very complicated. This method is appropriate for jumps that are too long for track kick, but too short for FG sled move. The principle behind speed control is almost the same as speed control track jump. The only difference is that the control output is not only track drive (TRD), but includes the sled drive (SLD). The maximum speed of this method is 151.2/4kHz . INITIALIZE : When HDWcmd's SNS = "L", INIcmd's SMM = "H" and JPMcmd is received, a speed control track jump is carried out for the number given by command. Other initial conditions are same as those in track jump using kick/brake. COMMAND JMPcmd (A6xxxx). TIMING DIAGRAM

MIRR/TZC SPEED CONTROL SLED MOVE 2 Summary Like speed control sled move 1, this method also uses TZC/MiRR in the detection signal. However, this method only uses sled drive (SLD) as the control output, so it is appropriate for jumps where a high speed sled speed is required. The principle for speed control is almost the same as that of sled move 1, only excepting that the control output controls only sled drive (SLD) and that actual MIRRs are counted instead of between the edges of MIRRs. This method is usually used for long distance move, and the maximum speed is the same as MIRR or TZC's maximum speed from the RF IC. Therefore, when using this method, you need a high quality MIRR at high speeds. INITIALIZE When HDWcmd's SNS = L, INIcmd's SMM = H and JPMcmd is received, speed control track jump is carried out for the number of tracks given by command. Other initial conditions are the same as those in track jump using kick/brake. Executable COMMAND JMPcmd (A6xxxx). Operation Description The speed can be controlled by selecting before hand the speed you want (number of MIRR) and counting the number of MIRR for measuring the deviance and sending feedback to the sled drive (SLD) level. You can move the tracks at the speed you want using the internal counter clock to count the TZC or MIRR input into DSSP.

FG PULSE CONTROL SPEED SLED MOVE Summary This method is an FG speed control (INIcmd's SMM = "H") sled move when you can use the FG pulse as a way to measure the number of tracks being moved. The principle of speed control is almost the same as that of speed control track jump. The difference is that the speed detection signal is not MiRR but FG (PS1& PS0), and the control output is not TRD, but SLD. This method is also used for long distance moves. INITIALIZE When HDWcmd's SNS = H, INIcmd's SMM = H and JPMcmd is received, track jump is carried out for the number of tracks given by command. Other initial conditions are the same as those in track jump using kick/brake. Execution COMMAND JMPcmd (A6xxxx). Operation Description The sled kick pulse is the SL_avrg before kick overlapped with SKCKd, which is output to SLD. The sled kick pulse reacts with the difference between the FG pulse's second edge and the speed profile's interval, so that the drive voltage is output to SLD. Speed control is carried out so that it matches the profile. Also, FG pulse is ENTc track, so if you have a short track search, the number of tracks moved becomes N immediately after speed control, making speed control useless.

WIDE CAPTURE RANGE PLL
Summary The channel clock restoration PLL supplies the system clock for restoring the EFM data in the DSP into its original signal components. The EFMI signal from the data slice has the form of RLL (3T - 11T, 14T) code. Restoring the clock in a signal means that you are extracting clocks with a period of T. The PLL being supplied follows the frequency change of the clock existing within 50% of the center frequency, allowing for playback speed improvement at track jump or other points when the data is incontinuous. It can also be used with the CAV control method. The built-in features include the following: CD 1/2/4/8x and DVD 1x compatible Track jump and disc DFCT through PHOLD pin possible Uniform LPF regardless of speed Fast tracking through PWM generation during jump control PD, FD gain separation control using RPD and RFD (improves safety and speed)

The disc rotation speed in CAV mode is set by the following equation. DISC RPM = fsys x 10 x Nck / 1024 / CAV_REF where fsys : System Clock FOR DVD(27 MHz), FOR CD(33.8688/8 MHz) Nck : Clock division ratio set by CAVCKSEL[1:0] (8 128 division,4 256 division,2 512 division,1 1024 division) CAV_REF : Exists between 1408 A CAV_REF A 1537 through the value calculated by (1537- Ncarv)
CAV_ REF =
XTAL x 10 x Nck 1024 x RPM
where XTAL: DVD (XTL1) , CD (CK33M1/8) Example) CAVVAL(10:0) value for 1440 RPM CAV_REF = 26.16MHz x 10 x 8 = 1419.27 1419 1024 x 1440
CAVVAR = 1537 - 1419 = 118 = 76H
Be aware that the CAV_REF value calculated with the above equation can change with fsys.

For Servo: Micom Write Register & Read/Write Register Table (Samsung Pick-up Mecha Used) Action Command Commands A0-A6 are called action commands because they are directly related the actual servo and, if these commands are received during repeat jumps, they stop the jumps.

Furthermore, it can reduce the power consumption when the servo has stopped by lengthening the ssp1611 frequency, and it can turn on/off the laser diode. (It first checks to see if STOP>ABRT. IDLE and LDX are the same.) STOP reserve waits to stop the operating mode. When STOP is reserved, re-pull_in is not allowed. When MON signal becomes low, the servo enters the real stop mode. However, if the stop cmd (A080) is re-executed during reserve stop, then the servo immediately stops. N When STOP = 1 and ABRT = 0, the servo is initialized and automatically controlled values do not change. When STOP = 1 and ABRT = 1, the servo is initialized and automatically controlled values change. Sometimes, it is used during tray off. 0 0 0 0 STOP mode reserve.
