TDA8752A Overview
GENERAL DESCRIPTION TDA8752A The TDA8752A is a triple 8-bit ADC with controllable amplifiers and clamps for the digitizing of large bandwidth RGB signals. The clamp level, the gain and all of the other settings are controlled via a serial interface (either I2C-bus or 3-wire serial bus, selected via a logic input). The IC also includes a PLL that can be locked on the horizontal line frequency and generates the ADC...
TDA8752A Key Features
- Triple 8-bit ADC
- Sampling rate up to 100 MHz
- IC controllable via a serial interface, which can be either I2C-bus or 3-wire, selected via a TTL input pin
- IC analog voltage input from 0.4 to 1.2 V (p-p) to produce full-scale ADC input of 1 V (p-p)
- 3 clamps for programming a clamping code between -63.5 and +64 in steps of 1⁄2LSB
- 3 controllable amplifiers: gain controlled via the serial interface to produce a full scale resolution of 1⁄2LSB peak-to
- Amplifier bandwidth of 250 MHz
- Low gain variation with temperature
- PLL, controllable via the serial interface to generate the ADC clock, which can be locked to a line frequency from 15 to
- Integrated PLL divider
