RX IF/BBA WITH AGC

S1M8656A

1

INTRODUCTION

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.

Its operating voltage is 2.7V – 3.6V, and operating temperature

-30

°C – +85°C .
