BCM3551
ITU656
Highly-integrated solution combining the functionality of a
complete television on a single chip.
Superior ATSC signal reception and demodulation under both
static and dynamic multipath conditions.
Integration of field proven QAM and out-of-band receivers.
PEP advanced video signal processing provides an elevated
viewing experience through edge and color enhancements.
Motion adaptive per pixel deinterlacing produces superior
display of interlaced video on progressive displays.
3D/2D comb filter with per pixel adaptive motion detection
delivers superior Y/C separation.
High quality on-chip video scaling provides extensive non-
linear conversion of 4:3 images for display on 16:9 televisions.
On-chip support to convert all inputs (480i, 480p, 720p, 1080i)
to all outputs (480i, 480p, 720p, 1080i) in both digital and
analog formats.
Advanced graphics engine provides rich user interface
environment.
Direct 10-bit digital video support for interfacing with LCD,
Plasma, and DLP panels preserves signal integrity and image
quality.
Comprehensive integration of A/Ds and DACs supports direct
audio/video inputs/outputs simplifying system design and cost.
Full peripheral support eliminates need for additional
components including, USB 2.0, LED/Keypad, smartcard,
BSC/SPI master, IR receiver/blaster, PWM, and dual UARTs.
