11 / 15 page LA75503V No.6804-11/15 Continued from preceding page. Pin No. Pin name Pin function Equivalent circuit 20 1st SIF INPUT Pin 20 can be used both as the First SIF IN and inter/split switch pins. In the case of inter carrier, connect pin 20 to GND. When a sound saw filter is added, the matching loss can be decreased by inserting L to neutralize the IC input capacitance and saw filter output capacitance. 21 VCC Connect the decoupling capacitor as close as possible. 22 GND 23 24 VIF INPUT Pins 23 and 24 are VIF input pins. To reduce the loss of signal through a saw filter, input resistors are set to 2k Ω. VIF amplifier has three capacitive coupling amplifiers, direct connection from a saw filter is available.
