TDA9955HL

The TDA9955HL is designed as one kind of triple 8-bit analog-to-digital video converter device that converts an RGB analog signal into a RGB or YUV (YCBCR) digital signal and supports analog TV resolutions from 480i (720 x 480i at 60 Hz) to High-Definition TV (HDTV) (up to 1920 x 1080p at 60 Hz). And this device can be used in (1)Set Top Box (STB); (2)YUV or RGB high-speed video digitizer; (3)Projector, plasma and LCD TV; (4)Rear projection TV; (5)High-end TV applications.

Features of the TDA9955HL are:(1)Triple 8-bit Analog-to-Digital Converter (ADC); (2)Three independent analog video sources, up to 170 MHz selectable via the I2C-bus; (3)Analog composite sync slicer and recognition integrated; (4)Frame and field detection for interlaced video signal; (5)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); (6)Three clamps for programming a 8-bit clamping code from 0 to +191 in steps of 1 LSB for RGB and YUV signals; (7)Three video amplifiers controlled via I2C-bus to reach the full-scale resolution; (8)Amplifier bandwidth of 100 MHz; (9)Low gain variation with temperature; (10)IC controlled via the I2C-bus, 5 V tolerant and bit rate up to 400 kbit/s.

The absolute maximum ratings of the TDA9955HL can be summarized as:(1)supply voltage on all 3.3 V pins: -0.5 to +4.6 V;(2)supply voltage on all 1.8 V pins: -0.5 to +2.5 V;(3)supply voltage difference: -0.5 to +0.5 V;(4)output current: 35 mA;(5)storage temperature: -40 to +125 °C;(6)ambient temperature: 0 to 70 °C;(7)junction temperature: 150 °C;(8)electrostatic discharge voltage: 2000 V.
