RX IF/BBA WITH AGC
S1M8656A
INTRODUCTION
48-LQFP-0707
S1M8656A/8657 are CDMA/AMPS Dual Mode IF/ baseband IC which is
divided into three main parts - IF frequency processing, basband
processing , and digital interface. The receiver IC (S1M8656A)and
transmitter IC (S1M8657) are provided as a KIT.
S1M8656A is a receiver IC, installed with a Rx AGC, Baseband
Converter, Baseband analog filter, and A-D Converter. It can send a
digital baseband signal to the digital baseband IC. The S1M8657X01 is a
transmission-only IC, installed with a Tx AGC, IF frequency converter,
analog filter, D-A Converter, PLL, 8-bit A-D Converter for the system
monitor, and 3-input analog switch. It connects the digital baseband IC to
the RF processing. Designed to operate in direction connection with the
MSM, S1M8656A and S1M8657 are fabricated on the Samsung's 0.5um
high-speed, high-frequency BICMOS processing and can achieve
superior high frequency and low power digital operations.
