Confidential TMPA8873PSNG /CMNG /CPNG /CRNG /CSNG Signal Processor Descriptions 1. Tank-Coil-Less PIF VCO TMPA8873 adopts a tank-coil-less PIF VCO circuit, which has advantages of cost, performance of weak IF input and easy to design PCB layout. The PIF PLL system has self-alignment circuit, so that the micro controller needs only to order the PIF PLL system to start self-alignment through the IIC bus.

Confidential TMPA8873PSNG /CMNG /CPNG /CRNG /CSNG 6. AV Switch The audio switch has two inputs for an external audio, and one for internal demodulated audio signal. The two external audio inputs can use as audio stereo input. The switched audio signal goes into the audio attenuator, which has controllability of audio gain from 0dB to –80dB or less with near log curve characteristic.

Confidential TMPA8873PSNG /CMNG /CPNG /CRNG /CSNG 13. Signal Detection Flags There are some flags on the READ BUS registers. They indicate that a certain signal is detected at the moment. But reliability of a detection result is not so accurate if checking only one flag, so that confirming several flags, which means similar result by each other, at the same time is recommended.
