5 / 15 page 5 Video ICs BA7357S 7 VIFA 6 VIFB IN 4.2V 8 GND2 — — 0V IN 6.6V — 2.7V — 5.2V 9 SIF 10 AFC 11 VO4.5M Standard voltage IN / OUT Video IF input. Use with balanced input. SIF and PLL GND. Audio IF input. Can set to intercarrier mode by pulling down via a 2k Ω resistor. Terminal for holding the audio output DC level fixed. Connect to GND via a 4.7 µF capacitor and to Vreg via a 10 µF capacitor to reduce BUZZ. Set this pin to 0.3V or lower to apply Audio / Video Mute. 2nd SIF output. Connect a Trap to this pin to vary the Sound Filter characteristics. The internal impedance is a high (Approximately) 1k Ω, so connect a Buffer to output. Pin name Pin No. Function Equivalent circuit 5 7 VCC GND 1k 1k 1k 5.3k 5.3k 9 20k 15k 15k 17pF VCC GND 10 3.5V 40k VCC GND 11 VCC GND Sound Filter 8k |
