Product speciﬁcation

Triple high-speed Analog-to-Digital

Converter (ADC)

TDA8752A

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)

GENERAL DESCRIPTION

The TDA8752A is a triple 8-bit ADC with controllable

amplifiers and clamps for the digitizing of large bandwidth

RGB signals.

• 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

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).

• Amplifier bandwidth of 250 MHz

The IC also includes a PLL that can be locked on the

horizontal line frequency and generates the ADC clock.

The PLL jitter is minimized for high resolution PC graphics

applications. An external clock can also be input to the

ADC.

• 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 280 kHz

• Integrated PLL divider

It is possible to set the TDA8752A serial bus address

between four fixed values, in the event that several

TDA8752A ICs are used in a system, using the I²C-bus

interface (for example, two ICs used in an odd/even

configuration).

• 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 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.
