Signals output from AMP with AGC will go through an external quartz resonator, which serves as a band-pass filter, and will be amplified again at AMP. AMP with AGC AMP Crystal (2) AGC Block Output signals from AMP will be input to the AGC block and the rectifier block. After signals are input to the AGC block, their high side peak amplitudes are detected. As AGC signals, they will be fed back to AMP with AGC. The AGC block has the AGC hold function. When the AGC hold signal is "H," the block performs the regular AGC operation. The AGC block performs the AGC hold operation when the AGC hold signal is "L." AGC signal (To AMP with AGC) AGC (3) Rectifier Block After signals are input to the rectifier block, their high side peak amplitudes are detected. As DET signals, they will be transferred to the slicer block. DET signal (to slicer block) Rectifier 7/11 PEDL6190A-03 OKI Semiconductor ML6190A (4) Slicer Block Signals output from the rectifier block are input to the slicer block and will be shaped to VDD as “1” and GND as “0”. Then, these outputs will be output as time codes (TCO). This LSI has the standby function. When the PON signal is "H," the LSI will perform the regular operation. When the PON signal is "L," the LSI will be in standby state. The TCO during the standby state is "H." VDD (5) Time Code Output The time code output (TCO) of the ML6190A is in phase with actual time codes input from the antenna. A “H” level is output for the large amplitude signal and a “L” level is output for the small amplitude signal.
