HA12155NT/HA12157NT
Audio Signal Processor for Cassette Deck (Dolby B/C-type NR with Recording System)
ADE-207-115C (Z) 4th Edition June 1997 Description
HA12155NT/HA12157NT is silicon monolithic bipolar IC providing Dolby noise reduction system*, electrical volume system, REC equalizer system and level meter system in one chip.
Functions
* REC equalizer * Dolby B/C NR * Electronic volume * Level Meter x 2 channel x 2 channel x 2 channel x 2 channel
Features
* Inductor less REC equalizer is adjustable of its characteristics by external resistor * Rec level is adjustable automatically with electrical volume which is built-in * 3 type of input selection is available (one is by way of electrical volume) * Separate input selection SW and REC/PB SW * Dolby noise reduction with dubbing cassette decks (Unprocessed signal output available from recording out terminals during PB mode) * Log-compressed level meter output is range from 0 V to 5 V (Usable as music search switchable gain of 0 dB and 20 dB respectivily) * Normal-speed/high-speed (Double), normal/metal/chrome fully electronic control switching built-in * NR-ON/OFF, Dolby B/C, MPX ON/OFF fully electronic control switching built-in (Controllable from micro-controller directly) * Reduction of number of pin by transfered serial data to electronic volume control switching and another control switching (Controllable from micro-controller directly) * Low external parts count

Application Note
Power Supply Range HA12155NT/HA12157NT are designed to operate on either single supply or split supply. The operating range of the supply voltage is shown in table 1. Table 1
Type No. HA12155NT HA12157NT
Supply Voltage
Single supply 9.5 V to 16 V 12 V to 16 V Split supply 6 V to 8 V 6 V to 8 V
The lower limit of supply voltage depends on the line output reference level.
Rev.4, Jun. 1997, page 13 of 57
HA12155NT/HA12157NT
The minimum value of the headroom margin is specified as 12 dB by Dolby Laboratories. HA12155 series are provided with two line output level, which will permit an optimum headroom margin for power supply conditions. Reference Voltage For the single supply operation these devices provide the reference voltage of half the supply voltage that is the signal grounds. As the peculiarity of these devices, the capacitor for the ripple filter is very small about 1/100 compared with their usual value.

Notes: 1. Voltages shown above are determined by internal circuits of LSI when take pin 55 (DGND pin) as reference pin. On split supply use, same VTH can be offered by connecting DGND pin to GND pin. This means that it can be controlled directly by micro processor. 2. Each pins are on pulled down with 100 k internal resistor. Therefore, it will be low-level when each pins ar open. 3. Note on serial data inputting (a) The clock frequency on CLK must be less than 500 kHz. (b) Over shoot level and under shoot level of input signal must be the value shown below. (c) The serial input pins (pins 62, 63, and 64) are extremely sensitive to undershoot, overshoot, ringing, and noise. This can result in malfunctions due to problems with the wiring pattern. We recommend attaching capacitors in parallel with the serial input pins to ameliorate this problem. Figure 2-b shows an example of this circuit appropriate when the clock frequency is 500 kHz. The value of the capacitor should be set in accordance with the clock frequency actually used. 4. NR Mode Switching In actual use, pop noises may accompany NR on/off switching in C mode. To avoid these noises, use the following sequences to turn NR on and off. From C mode NR off to C mode NR on: (C mode, NR off) (B mode, NR off) (B mode, NR on) (C mode, NR on). From C mode NR on to C mode NR off: (C mode, NR on) (B mode, NR on) (B mode, NR off) (C mode, NR off).

When connecting microcomputer or Logic-IC with HA12155NT/HA12157NT directly, there is apprehension of rash-current under some transition timming of raising voltage or falling voltage at VCC ON/OFF. For this countermeasure, connect 10 k to 20 k resistor with each pins. It is shown in test circuit.

MPX ON/OFF Switch MPX-OFF mode means that signal from input amp doesn't go through the MPX filter, but signal goes through the SS circuit after being attenuated 3 dB by internal resistor. Refer to figure 5. For not cause any level difference between MPX-ON mode and MPX-OFF mode, it is requested to use MPX-filter which has definitely 3 dB attenuated. MPX-OFF mode offer totally flat frequency response and no bias-trap effect. And when applying other usage except figure 5, take consideration to give bias voltage to NR-IN terminal by resistor or so on because internal of NR-IN terminal hsa no bias resistor.

Figure 6 Application for Dubbing Deck Injector Current HA12155NT/HA12157NT has logic circuit which is fabricated by I L into IC. To operate this circuit, it is required enough injector current. Injector current goes into from the INJ pin (pin 10) and external resistor is required to connect to this pin for adequate current. The value of external resistor is obtained by using following equations. And put them with 10% tolerance value which is calculated. VINJ can allow to connect to VCC shown below. Under the condition of high temperature, the mis-operation of logic is caused by large injector current. Also, under the condition of low temperature, the stop of logic is caused by small injector current. Therefore, pay attention to have good stability of VINJ.

Gain Control of Electronic Volume HA12155NT/HA12157NT is designed in order to change the gain by 6 bit DAC fabricated into IC. To reduce the click noise when changing volume gain instantaneously, required to connect the capacitor (CR time constant) to CNT pin (pin 6,59). These terminals are also be used as output pin of DAC. Therefore, by forcing voltage or current to these terminals, it is applicable to control volume gain directly. But, voltage forced to these terminals must be from VCC/2 -2 V to VCC/2 (for split supply use, -2 V to 0 V) in this case. In case of forcing the current these pins, voltage must be the value mentioned above even it is 20% distributed of internal resistor (5.2 k) of CNT pin. And, these case, change of a gain depending on a temperature gets large.
