Sunnyvale, CA 94086-5305 11/05 IN CAS-220 DVD Digital Camera Digital TV Imaging IP Core Driving the Digital LifestyleDriving the Digital Lifestyle The Cascade2 is a multistandard demodulator and decoder for terrestrial and cable TV reception. It is designed to support 8/16-VSB in compliance with the ATSC Digital Television Standard as well as OpenCable ITU-T J.83B in compliant 256/64 QAM and OOB QPSK modes for Digital Cable Ready downstream reception. The Cascade2 is designed to reduce system costs by integrating the FAT channel demodulation of VSB, J.83 Annex B QAM and Audio decoding (for analog channels) and the FDC QPSK channel demodulation. The small, high-performance Cascade2 is well suited for any system designed to receive off-air and cable digital TV transmissions. This includes stand-alone SDTV or HDTV sets, Set-Top Boxes, PC-TV cards and data reception appliances. The Cascade2 family ICs are produced in several combinations of reception standards: Cascade2 P/N Decscription ATSC QAM Annex B OOB FDC US Audio BTSC Korea Audio A2FM FM Radio Smart Antenna CAS-220 VSB • • CAS-220/C VSB, QAM • • • CAS-220/S VSB, BTSC • • • • • CAS-220/CS VSB, QAM, BTSC • • • • • • CAS-220/CO VSB, QAM, OOB • • • • CAS-220/CSO VSB, QAM, BTSC,OOB • • • • • • • System Block Diagram Cascade2 25MHz MPEG 2TS Host I2C I2S Data Audio IF AGC PWM LPF BPFSAW filter and IF AGC Tuner NTSC demod IF 44MHz ADC ADC 2nd IF Sound (4.5 MHz) Tuner I2C SIF (Option) FM IF (Option) CVBS Cascade2 front end system solution without OOB Mixer OOB tuner FDC IF Input Local Oscillator 25MHz VSB SAW Tuner I2C FAT IF Input BTSC 4.5 MHz CVBS Tuner Antenna Spliter 54-860MHz LNA Cable In/Out BPF IF 44MHz BPF 70-130 MHz Cascade2 FAT - Forward App Transport Cascade2 front end system solution with OOB AGC Serial MPEG2 Transport 10-bit ADC FAT AGC IF Input SIF Input FDC AGC Programmable Digital Filters and other DSP Blocks Firmware RAM FEC Parallel MPEG 2 TS Out 10-bit ADC FDC QPSK Demodulator Sound Decoder FDC IF In LOFDC LO ADC AGC DSP Parallel MPEG 2 TS In Host IIC General Purpose I /O Pins IIS Output FDC data Out MPEG2 Mux and Serializer Mux SwitchTuner IIC Main PLLOscCLK0 Internal Clocks
