S1M8662A

RX IF/BBA WITH GPS S1M8662A (Preliminary) INTRODUCTION S1M8662A is CDMA/PCS/GPS Triple Mode IF/ baseband IC which is divided into three main parts - IF frequency processing, basband processing , and digital interface. The receiver IC (S1M8662A)and transmitter IC (S1M8657) are provided as a KIT. S1M8662A 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. S1M8662A is 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 2.7 to 3.3V, and operating temperature -30 to +85°C . 32-BCC++-5.0×5.0 FEATURES Cellular CDMA/PCS/GPS Triple Mode AGC input signal range : 90dB 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 VCO for baseband conversion Built-in Modem PDM control circuit to compensate the I and Q offsets Built-in TCXO output ON/OFF 3-Line Serial Port Interface (SPI) Operating Voltage : 2.7 to 3.3V 32BCC++(5mm * 5mm * 0.8mm) Package ORDERING INFORMATION Device ++ S1M8662AX01-F0T0 ++ : Under Development Package 32-BCC++-5.0×5.0 Operating Temperature -30 to +85°C 1 S1M8662A (Preliminary) RX IF/BBA WITH GPS BLOCK DIAGRAM RXVCO_OUT1,2 RXVCO_T1 RXVCO_T2 VCO CDMA LPF GPS LPF 0 I_OFS SPI ...
