RC6508

RC6508 QAM IF Downconverter Electronics Semiconductor Division Features Integrated IF Down Converter IF bandwidth from 30 MHz to 80 MHz Operating range between 8.5V to 13.2V 63dB peak conversion gain from IF to baseband 40dB minimum AGC range Simple interface to SAW filter and A/D converter Gain control minimizes noise figure and distortion Tuner control feature interfaces with variety of tuners Industry standard 24 Lead SSOP package Applications Digital Set-top Receivers Cable Modems Description The RC6508 simplifies the front-end design of cable modem and set-top receivers. It is a cost-effective solution, since it integrates IF amplifier, AGC, mixer, amplifier, tuner AGC, VCO, XTAL OSC, and bandgap reference on a single chip. The RC6508 downconverts the IF signal to baseband signal for cable modem and set top receivers. The baseband signal can be digitized and decoded with an external A/D converter and a custom DSP demodulator. The...
