GENERAL DESCRIPTION
The TDA8753A is a monolithic CMOS 8-bit video low-power analog-to-digital conversion interface for YUV signals. It converts the YUV analog input signal into 8-bit binary coded digital words in format 4 : 1 : 1 at a sampling rate of 20 MHz. All analog signal inputs are clamped. The device includes a digital sample rate converter for variable compression with a factor 1 to 2.

FEATURES
• Triple analog-to-digital converter
• 8-bit resolution
• Sampling rate up to 20 MHz
• Power dissipation of 500 mW (typical)
• Internal clamp functions
• 4 : 1 : 1 output data encoder
• Y binary output
• U, V twos complement outputs
• Sample rate converter permits programmable horizontal compression factors from 1 to 2
• Serial microcontroller interface
• TTL compatible inputs.

APPLICATIONS
• High-speed analog-to-digital conversion for video signal digitizing in 4 : 1 : 1 format
• 100 Hz improved definition TV for all formats (4/3, 16/9, 14/9 etc.).
