APPLICATIONS
GENERAL DESCRIPTION
The TDA8755 is a bipolar 8-bit video low-power
analog-to-digital conversion (ADC) interface for YUV
signals. The device converts the YUV analog input signal
into 8-bit coded digital words in a 4 : 1 : 1 format at a
sampling rate of 20 MHz. The U/V signals are converted in
a multiplexed manner. All analog signal inputs are digitally
clamped and a fast precharge is provided for start-up.
All digital inputs and outputs are TTL compatible. Frame
synchronization is supported in a multiplexed manner.
High speed analog-to-digital conversion for video signal
digitizing
100 Hz improved definition TV (IDTV).
