NXP Semiconductors TDA8754
The TDA8754 is a triple 8-bit ADC with controllable gain and clamps for the digitizing of large bandwidth R, G, B signals. The gain is optimized for stability versus temperature variations. The IC also includes a PLL that generates the ADC clock which can be locked to the horizontal line frequency.| Part No. | TDA8754 |

FEATURES
● Triple 8-bit Analog-to-Digital Converter (ADC)● Sampling rate up to 170 MHz
● IC controllable via a serial interface, which can be either I2C-bus or 3-wire, selected via a TTL input pin
● IC analog input 0.5 to 1.1 V (peak-to-peak value) to have full-scale ADC input
● Clamps for programming a clamp level through a clamping code between −63 and +64 by steps of 1 LSB
● Controllable gain stages: gain controlled independently on the 3 channels via the serial interface to have a full-scale resolution to 1%
● Low gain variation at different temperatures
● Analog bandwidth of 400 MHz
● Controllable PLL via the serial interface generates the ADC clock. It can be locked on line frequencies from 15 kHz up to 280 kHz.
● Integrated PLL divider
● Integrated clamp pulse and H and V LCD control pulses generation (independently adjustable in position and duration). Also a data enable signal can be generated, independently adjustable in position and duration with respect to HSYNC.
