The BCM3560 combines a cable/terrestrial 4/1024-QAM and 8/16-VSB receiver, an out-of-band QPSK receiver, NTSC demodulator, DVI/HDMI receiver, a transport processor, a digital audio processor, a high-definition (HD) MPEG video decoder, 2D graphics processing, digital processing of analog video and audio, analog video digitizer and DAC functions, stereo high-fidelity audio DACs, a 250-MHz MIPS processor, and a peripheral control unit providing a variety of television control functions. The cable/terrestrial receiver directly samples a tuner output with an A/D converter. It digitally resamples and demodulates the signal with recovered clock and carrier timing, filters and equalizes the data, and passes soft decisions to an ATSC A/53 and ITU-T J.83 Annex A/B/C compatible decoder. A CEA/EIA-909 smart antenna interface is included on chip. The out-of-band receiver and mixer directly sample and digitize a SAW centered IF. It demodulates the signal with recovered clock and carrier timing, filters and equalizes the data and incorporates a DigiCipher(R) II/ DAVIC-compatible FEC decoder. The common hardware interface provides a direct interface to a POD/CableCard.
BCM3560 has an MPEG-2 DVB compliant transport processor with advanced section filtering capability, DVB descrambler, MPEG-2 (MP@HL profile) video decoder, a BTSC audio decoder, a Dolby AC3/MPEG-2 layer 1, 2, audio decoder with SPDIF and a pair of analog outputs (L-R), a single NTSC/PAL/SECAM video encoder with Macrovision(R) and analog output, Dual NTSC analog video decoders. The first NTSC/PAL decoder is supported by motion adaptive deinterlacing and a 3D comb filter. The second NTSC/PAL decoder supports PIP functionality utilizing a 2D comb. The BCM3560 includes Broadcom's advanced 2D graphics processing. Two transport stream inputs, one ISO7816 smart card interface and a high speed interface supporting 1394 are included. T h e B C M 3 56 0 i n c o r p or a t e s a c om p l e t e M I P S 3 2 TM b a s e d microprocessor subsystem including caches with bridging to memory and a local bus, where external peripherals can be attached. Integrated peripherals include two UARTS, counter/timers, GPIO, keypad, LED, IR Tx/Rx, IR Keyboard, BSC (I2C) and SPI controllers
