3 / 8 page MITSUBISHI ICS (TV) M64894FP/GP SERIAL INPUT PLL FREQUENCY SYNTHESIZER FOR TV/VCR 3 DESCRIPTION OF PIN ABSOLUTE MAXIMUM RATINGS (Ta=-20 °C to +75°C, unless otherwise noted) RECOMMENDED OPERATING CONDITIONS (Ta=-20 °C to +75°C, unless otherwise noted) Pin No. Symbol Pin name Function 1 fin Prescaler input Input for the VCO frequency. 2 GND GND Ground to 0V. 3VCC1 Power supply voltage 1 Power supply voltage terminal. 5.0V ±0.5V 4VCC2 Power supply voltage 2 Power supply for band switching, Vcc1 to 13.2V 5 6 7 8 BS4 BS3 BS2 BS1 Band switching outputs PNP open collector method is used. When the band switching data is "H", the output is ON. When it is "L", the output is OFF. 9 Vin Filter input (Charge pump output) This is the output terminal for the LPF input and charge pump output. When the phase of the programmable divider output (f 1/N) is ahead compared to the reference frequency (fref), the "source" current state becomes active. If it is behind, the "sink" current becomes active. If the phases are the same, the high impedance state becomes active. 10 Vtu Tuning output This supplies the tuning voltage. 11 VCC3 Power supply voltage 3 Power supply voltage for tuning voltage 28 to 35V 12 ADC/ftest AD converter input/ Test port A/D conversion of the input voltage. In control byte data input, the programmabule freq. Divider output and reference freq. output is selected by the test mode. 13 SCL Clock input Data is read into the shift register when the clock signal falls. 14 SDA Data input Input for band SW and programmable freq. divider set up. In lead mode, itoutputs lock detector output and power down flagand a state of 5 level A/D converter. 15 ADS Address switching input Chip address sets it up with the input condition of terminal. 16 Xin This is connected to the crystal oscillator 4.0MHz crystal oscillator is connected.
