GENERAL DESCRIPTION

The

analog-to-digital converter (ADC) with an on-chip sample-

and-hold circuit designed for low cost, low power, small size,

and ease of use. The product operates at a conversion rate of

up to 125 MSPS and is optimized for outstanding dynamic

performance and low power in applications where a small

package size is critical.

The ADC requires a single 1.8 V power supply and LVPECL-/

CMOS-/LVDS-compatible sample rate clock for full performance

operation. No external reference or driver components are

required for many applications.

The ADC automatically multiplies the sample rate clock for the

appropriate LVDS serial data rate. A data clock output (DCO) for

capturing data on the output and a frame clock output (FCO)

for signaling a new output byte are provided. Individual-channel

power-down is supported and typically consumes less than 2 mW

when all channels are disabled. The ADC contains several features

designed to maximize flexibility and minimize system cost, such
