General description

The TDA9955HL is a triple 8-bit video converter interface.

The TDA9955HL converts an RGB analog signal into a RGB or YUV (YCBCR) digital

signal or converts a YUV (YPBPR) analog signal into a YUV (YCBCR) or RGB digital signal

with a sampling rate up to 170 MHz.

The TDA9955HL supports analog TV resolutions from 480i (720

× 480i at 60 Hz) to

High-Deﬁnition TV (HDTV) (up to 1920

× 1080p at 60 Hz) and analog PC resolutions from

VGA (640

× 480p at 60 Hz) to UXGA (1600 × 1200p at 60 Hz).

The YUV digital output signal can be 4 :4:4 or 4:2:2 ITU-R BT.656 standard or

semi-planar format following the ITU-R BT.601 standard.

All settings are controlled via the I2C-bus.

Features

I Triple 8-bit Analog-to-Digital Converter (ADC)

I Three independent analog video sources, up to 170 MHz selectable via the I2C-bus

I Analog composite sync slicer and recognition integrated

I Frame and ﬁeld detection for interlaced video signal

I Video analog voltage input from 0.45 V to 0.9 V (p-p) to produce a full-scale ADC input

of 1.0 V (p-p)

I Three clamps for programming a 8-bit clamping code from 0 to +191 in steps of 1 LSB

for RGB and YUV signals
