BCM3552/BCM3553 WXGA AND FULL HD 1080P DIGITAL TV SYSTEM-ON-CHIP SOLUTIONS
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 decoder and a Dolby AC3/MPEG-2 Layer 1, 2, audio decoder with Trusurround XT support. The BCM3552/BCM3553 provides analog and digital audio/video outputs. Single (for WXGA) and dual (for Full HD 1080p) bbbb 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 bbbbb up to UXGA 1600 x 1200 is supported with auto phase and mode detection. Two independent HDMI receivers each support 1080p 60 fps bbbbbs. The BCM3552/BCM3553 includes Broadcom’s advanced 2D graphics processing. Two transport stream bbbbbs, 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.
