General Description

The CDK2307 is a high performance, low power dual Analog-to-Digital Con-

verter (ADC). The ADC employs internal reference circuitry, a CMOS control

interface and CMOS output data, and is based on a proprietary structure.

Digital error correction is employed to ensure no missing codes in the com-

plete full scale range.

Several idle modes with fast startup times exist. Each channel can be inde-

pendently powered down and the entire chip can either be put in Standby

Mode or Power Down mode. The different modes are optimized to allow the

user to select the mode resulting in the smallest possible energy consumption

during idle mode and startup.

The CDK2307 has a highly linear THA optimized for frequencies up to 70MHz.

The differential clock interface is optimized for low jitter clock sources and

supports LVDS, LVPECL, sine wave and CMOS clock inputs.
