• Manufacturer Part Number: bcm3560
• Description: Bcm3560 - Digital Tv System-on-chip
• Manufacturer: Broadcom Corp.

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 digitizes a SAW centered IF. It demodulates
the signal with recovered clock and carrier timing, filters and equalizes
the data and incorporates a DigiCipher
decoder. The common hardware interface provides a direct interface to a
POD/CableCard.

The 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 optional
Macrovision
NTSC/PAL decoder is supported by motion adaptive de-interlacing 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 is included.
The BCM3560 incorporates a complete MIPS32™-based
microprocessor subsystem including caches with bridging to memory
and a local bus, where external peripherals can be attached. Integrated
peripherals include USB 2.0, three UARTs, counter/timers, GPIO,
keypad, LED, IR Tx/Rx, IR Keyboard, BSC, and SPI controllers.
