bcm3553 Broadcom Corp., bcm3553 Datasheet - Page 2

• Manufacturer Part Number: bcm3553
• Description: Full High-definition 1080p Digital Tv System-on-a-chip
• Manufacturer: Broadcom Corp.

The 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 millions of
instructions per second (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
analog-to-digital (ADC) 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 surface acoustic wave (SAW)
centered interface (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
M-Card™/CableCARD™ device.
The BCM3553 has an MPEG-2 Digital Video Broadcasting (DVB)-
compliant transport processor with advanced section filtering capability,
DVB descrambler, and an MPEG-2 (MP@HL profile) video decoder.

Audio support includes both a BTSC/Korean A2 audio decoder and a
Dolby AC3/MPEG-2 Layer 1, 2, audio decoder with TruSurround XT
support.
The BCM3553 provides analog and digital audio/video outputs. Dual-
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 is supported by its own motion adaptive
deinterlacing and 3D comb filtering, including 1080i deinterlacing.
Direct PC input up to UXGA 1600 × 1200 is supported with auto-phase
and mode detection. Two independent HDMI receivers each support
1080p 60-fps inputs.
The 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 BCM3553
incorporates a complete MIPS32
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, Broadcom Serial Control (BSC), and SPI controllers.
