Each band consists of a low noise preamplifier/mixer and local oscillator with an external varactor tuned tank. The band outputs share a common low impedance SAWF driver stage. Frequency selection is controlled by the on-board I2C bus frequency synthesizer. This block also controls four general purpose switching ports for selecting the prefilter/AGC stages. The SL2610 has high intermodulation intercept performance so offering high signal to spurious performance in the presence of higher amplitude interferers or in the presence of a wide bandwidth composite input signal. An output broadband level detect circuit is included for control of the tuner front end AGC.

It is intended primarily for application in all band terrestrial tuners and requires a minimum external component count. It contains all elements required for RF downconversion to a standard IF with the exception of external VCO tank circuits. The pin allocation is contained in Figure 1 and the block diagram in Figure 2. 1.1 Mixer/oscillator section In normal application the RF input is interfaced to the selected mixer oscillator preamplifier through the tuner prefilter and AGC stages. The mixer input is arranged such that the signal can be coupled either differentially or single-ended, and achieves the specified minimum performance in both configurations. Band input impedances and NF are contained in Figure 11 and Figure 12 respectively. The converter two tone input spectra are contained in Figure 13 and Figure 14. The preamplifier output then feeds the mixer stage where the required channel is image reject downconverted to the IF frequency. The local oscillator frequency for the downconversion is obtained from the on board local oscillator, which uses an external varactor tuned tank. Typical VCO applications are contained in Figures 8, 9, and 10. The output of the mixer is then fed to the converter output driver which presents a matched 200 load to an external IF shaping filter. differential The output of the shaping filter is then coupled into the IFAMP stage, which provides further gain and offers a 50 output impedance to interface direct with the tuner SAW filter. The SL2610 contains a broadband level detect circuit whose output can be used to control the tuner AGC. The target level of the AGC detector is controlled by the voltage applied to the AGCBIAS pin. The characteristic of the target level is given in Figure 18. 1.2 PLL Frequency Synthesizer The PLL frequency synthesizer section contains all the elements necessary, with the exception of a frequency reference and loop filter, to control a varicap tuned local oscillator, so forming a complete PLL frequency synthesised source. The device allows for operation with a high comparison frequency and is fabricated in high speed logic, which enables the generation of a loop with good phase noise performance. It can also be operated with comparison frequencies appropriate for frequency offsets as required in digital terrestrial (DTT) receivers. The LO signal is multiplexed from the selected oscillator section to an internal preamplifier which provides gain and reverse isolation from the divider signals. The output of the preamplifier interfaces direct with the 15-bit fully programmable divider which is of MN+A architecture, where the dual modulus prescaler is 16/17, the A counter is 4-bits and the M counter is 11 bits. The output of the programmable divider is fed to the phase comparator where it is compared in both phase and frequency domain with the comparison frequency. This frequency is derived either from the on-board crystal controlled oscillator or from an external reference source. In both cases the reference frequency is divided down to the comparison frequency by the reference divider which is programmable into 1 of 29 ratios as detailed in Table 1. The output of the phase detector feeds a charge pump and loop amplifier section which when used with an external loop filter integrates the current pulses into the varactor line voltage. The programmable divider output Fpd, divided by two and the reference divider output Fcomp, can be switched to port P0 by programming the device into test mode. The test modes are described in Table 5. 5 SL2610 2.0 Programming Data Sheet The SL2610 is controlled by an I2C data bus and is compatible with both standard and fast mode formats. Data and Clock are fed in on the SDA and SCL lines respectively as defined by I2C bus format. The synthesizer can either accept data (write mode), or send data (read mode). The LSB of the address byte (R/W) sets the device into write mode if it is low, and read mode if it is high. Tables 2 and 3 illustrate the format of the data. The device can be programmed to respond to several addresses, which enables the use of more than one synthesizer in an I2C bus system (Tables 2 and 3). Table 4 shows how the address is selected by applying a voltage to the `ADD' input. When the device receives a valid address byte, it pulls the SDA line low during the acknowledge period and during following acknowledge periods after further data bytes are received. When the device is programmed into read mode, the controller accepting the data must pull the SDA line low during all status byte acknowledge periods to read another status byte. If the controller fails to pull the SDA line low during this period the device generates an internal STOP condition which inhibits further reading. 2.1 Write mode With reference to Table 2, bytes 2 and 3 contain frequency information bits 214-20 inclusive. Byte 4 controls the reference divider ratio bits R4-R0 (Table 1), and the charge pump setting bits C1-C0 (Table 6). Byte 5 controls the IF select (Table 8), the band select function bits BS1-BS0 (Table 7), the switching ports P3-P0 and the test modes (Table 5). After reception and acknowledgement of a correct address (byte 1), the first bit of the following byte determines whether the byte is interpreted as a byte 2 or 4, a logic '0' indicating byte 2, and a logic '1' indicating byte 4. Having interpreted this byte as either byte 2 or 4 the following data byte will be interpreted as byte 3 or 5 respectively. Having received two complete data bytes, additional data bytes can be entered, where byte interpretation follows the same procedure, without re-addressing the device. This procedure continues until a STOP condition is received. The STOP condition can be generated after any data byte, if however it occurs during a byte transmission, the previous byte data is retained. To facilitate smooth fine tuning, the frequency data bytes are only accepted by the device after all 15 bits of frequency data have been received, or after the generation of a STOP condition. 2.2 Read mode When the device is in read mode, the status byte read from the device takes the form shown Table 3. Bit 1 (POR) is the power-on reset indicator, and this is set to a logic '1' if the Vcc supply to the device has dropped below 3V (at 25oC), e.g. when the device is initially turned ON. The POR is reset to '0' when the read sequence is terminated by a STOP command. When POR is set high this indicates that the programmed information may have been corrupted and the device reset to power up condition. Bit 2 (FL) indicates whether the device is phase locked, a logic '1' is present if the device is locked, and a logic '0' if the device is unlocked. 6 Data Sheet 2.3 Programmable features Function as described above. Function as described above. SL2610 Synthesiser programmable divider Reference programmable divider Band selection IF selection Charge pump current Ports P3-P0 The required mixer oscillator band and RF input is selected by bits BS1-BS0, within data byte 5, as defined in Table 7. The centre of the image reject passband is selected by IF as defined in Table 8. The charge pump current can be programmed by bits C1-C0 within data byte 4, as defined in Table 6. These are configured as NPN open collector buffers and programmed by bits P3P0. Logic `1' = on. Logic `0' = off (high impedance); default on power up. In test modes, when TE=1, ports P3-P0 respond according to T2-T0 respectively, and previously transmitted data is lost. The test modes are invoked by setting bits T2-T0 as described in Table 5.
