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.
PACKAGE
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.).
