S1M8656A Datasheet | Samsung Semiconductor

RX IF/BBA WITH AGC 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. Its operating voltage is 2.7V - 3.6V, and operating temperature -30°C - +85°C . 48-BCC-7.0×7.0 Features - - - - - - - - - - CDMA/AMPS Dual Mode AGC input signal range : 90d B QPSK Baseband Converter Built-in I ,Q Baseband signal extractor LPF Built-in 4-bit ADC for converting I and Q CDMA analog baseband signals to digital baseband signals Built-in 8-bit ADC for converting I and Q FM analog baseband signals to digital baseband signals Adopts the Rx SLOT function to minimize the AMPS Mode consumption power Built-in VCO for baseband conversion Built-in Modem PDM control circuit to pensate the I and Q offsets 3-Line Serial Port Interface (SPI) ORDERING INFORMATION Device + S1M8656A01-E0T0 + S1M8656A01-F0T0 + : New product Package 48-LQFP-0707 48-BCC-7.0×7.0 Operating Temperature -30 to +85°C RX IF/BBA WITH AGC BLOCK DIAGRAM I_OFS Q_OFS TCXO DIV.N/CHIPx8 TCXO/N CHIPx8 FMCLK FMSTB FMRID/RXID1 FMRQD/RXID0 2 2 4 CRX_IF1 CRX_IF2 RAGC_CONT FRX_IF1 FRX_IF2 1/2Div. 90D-PSN LPF LPF LPF LPF OFFSET...
