• Manufacturer Part Number: bcm3552
• Description: Bcm3552 - Wxga And Full Hd 1080p Digital Tv System-on-chip Solution
• Manufacturer: Broadcom Corp.

The BCM3552/BCM3553 combines a cable/terrestrial 4/1024-QAM and 8/16-
VSB receiver, an out-of-band QPSK receiver, NTSC demodulator, two DVI/
HDMI receivers, 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 330-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® II/ DAVIC-compatible FEC decoder. The common
hardware interface provides a direct interface to a MCard/CableCard device.
The BCM3552/BCM3553 has an MPEG-2 DVB compliant transport processor
with advanced section filtering capability, DVB descrambler, MPEG-2 (MP@HL
profile) video decoder. Audio is support includes both a BTSC/Korean A2 audio

The BCM3552/BCM3553 provides analog and digital audio/video outputs. Single
(for WXGA) and dual (for Full HD 1080p) link LVDS transmitters provide direct
digital connection to panel displays. A NTSC/PAL video encoder analog output
with Macrovision (optional) provides analog video for VCR out support. A SPDIF
output and a pair of analog outputs (L-R) are provided via the integrated audio DACs.
The NTSC analog video decoder supports motion adaptive deinterlacing and 3D
comb filtering including 1080i deinterlacing. Direct PC input up to UXGA
1600 x 1200 is supported with auto phase and mode detection. Two independent
HDMI receivers each support 1080p 60 fps inputs.
The BCM3552/BCM3553 includes Broadcom’s advanced 2D graphics
processing. Two transport stream inputs, one ISO7816 smart card interface, and a
high-speed interface supporting IEEE 1394 is included. The BCM3552/
BCM3553 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 two USB 2.0, three
UARTs, counter/timers, GPIO, keypad, LED, IR Tx/Rx, IR Keyboard, BSC, and
SPI controllers.
