GENERAL DESCRIPTION
The TDA8752B is a triple 8-bit ADC with controllable amplifiers and clamps for the digitizing of large bandwidth RGB signals.

FEATURES
• Triple 8-bit ADC
• Sampling rate up to 110 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 a 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-peak
• 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 of 15 to 280 kHz
• Integrated PLL divider
• Programmable phase clock adjustment cells
• Internal voltage regulators
• TTL compatible digital inputs and outputs
• Chip enable high-impedance ADC output
• Power-down mode
• Possibility to use up to four ICs in the same system, using the I2C-bus interface, or more, using the 3-wire serial interface
• 1.1 W power dissipation.

APPLICATIONS
• R, G and B high-speed digitizing
• LCD panels drive
• LCD projection systems
• VGA and higher resolutions
• Using two ICs in parallel, higher display resolution can be obtained; 200 MHz pixel frequency.
