Complementing its broad data converter and DVI receiver

offering for video interface, Philips Semiconductors portfolio

is now presenting a state-of-the-art combination of HDMI

receiver (High Definition Multimedia Interface) and analog-

to-digital video interface technology. This device enables TV

manufacturers to easily comply with the new HDMI standard

required for new generation TVs. At the same time, TV

makers remain compliant with all analog standards, from

PAL/NTSC interlaced to 720p and 1080i HDTV.

Triple 10-bit analog-to-digital video

interface with HDMI receiver for new

generation TVs up to 81 Msps

Description

The TDA9975 is optimized for new TV applications using YUV / RGB based

processors, either in CCIR656 or CCIR601 (YpbPr semi-planar) formats.

It combines an analog path with a triple 10-bit ADC up to 81 MSPS, and

a digital path with two selectable single link HDMI receivers. Both signal

paths are processed through a highly flexible digital block including a fully

programmable RGB to YUV—and reverse—matrix, down-sampling filters

and digital output formatters (including EAV / SAV information insertion in

case of CCIR 656). This enables users to choose RGB or YUV 4:4:4, YUV

4:2:2 (CCIR601 or 656) outputs, whatever is the best for their system. In

addition, there is no loss of resolution regardless of whether the inputs

are RGB, YUV or HDMI.

The TDA9975 includes a highly configurable sync separator, avoiding the

use of an external device. It is compatible with all standard analog video

sources from VCR to HDTV thru DVD and Set Top Box. A copy protection

scheme complying to the HDCP 1.1 (High-bandwidth Digital Content

Protection) standard is added to the interface. HDCP keys are loaded

via I

TDA9975 is packaged in a SQFP208 and LBGA256.

The TDA9974 includes the HDMI receiver and digital processing

functions of the TDA9975.

The TDA9970 includes the HDMI receiver function of the TDA9975,

combined with a 8-bit resolution analog path.
