GENERAL DESCRIPTION
The TDA8762A is a 10-bit high-speed analog-to-digital
converter (ADC) for professional video and other
applications. It converts the analog input signal into 10-bit
binary-coded digital words at a maximum sampling rate of
80 MHz. All digital inputs and outputs are TTL compatible,
although a low-level sine wave clock input signal is
allowed.
