| (R) QAMI5516 Single module demodulator and decoder IC for digital video set-top boxes DATA BRIEF Description The QAMI5516 is an integrated demodulator/decoder solution for digital cable receivers for compressed video, sound and data services. A QAM demodulator performs IF to MPEG-2 block processing of QAM carriers. The demodulated stream is then processed by video and audio decoders using standard Omega technology. The QAMI5516 contains all of the most commonly used descramblers, and thus allows a single platform to be developed to cover the entire mainstream set-top box market (USA, Europe, Asia) . Application: Highly cost-effective solution for digital cable set-top boxes Flash SDRAM (optional) SDRAM IR Tx/Rx Tuner IF in SSCn_DIN/DOUT SDA QAMI5516 RGB SSCn_SCLK SCL Serial/parallel TSOUT CVBS/YC TSIN1/2 RS232 VCR March 2004 1/2 QAMI5516 Features Decodes ITU-T J.83-Annexes A/B/C and DVBC bitstreams Integrated high performance ADC Support for 4-, 16-, 32-, 64-, 128-, 256-point constellation variable symbol Rate from 0.87 MBaud to 11.7 MBaud Robust integrated adaptative equalizer IC serial bus and IC repeater Lock time <100ms 180 MHz 32-bit ST20 CPU Graphics/display 5 display planes (background, video, still, OSD and cursor) 2, 4 and 8bpp CLUT graphics PAL/NTSC/SECAM video encoder RGB, CVBS, Y/C and YUV outputs with 10-bit DACs Encoding of CGMS, teletext, WSS, VPS, closed caption Macrovision 7.01 copy protection Interfaces CableCard and dual DVB common interface 5 ASCs (UARTs) with Tx and Rx FIFOs 8 Kbytes internal SRAM, 8 Kbytes of I-cache and 8 Kbytes of D-cache DES, DVB and ICAM descramblers Support for more than 48 PID slots Fully programmable horizontal and vertical SRCs Integrated transport demultiplexer 6 x 8-bit banks of parallel I/O 2 smartcard interfaces and clock generators 4 PWM channels Multichannel IR transmitter/receiver Low power/RTC/watchdog controller MPEG-2 MP@ML video decoder Module features Low power consumption (~1500 mW) Package: 27 x 27 mm 416 PBGA, 1 mm pitch Audio features MPEG-1 layers I/II decoding (MP3 option) Dolby Digital 5.1 down-mixed to 2 channels Dolby Pro Logic compatible TruSurround virtual surround sound SRS PCM audio input Integrated audio DACs Ordering information Device number QAMI5516AUA CBR1300 Description Integrated cable demodulator/decoder Development platform for QAMI5516 Information furnished is believed to be accurate and reliable.
