General Description

The CDK1307 is a high performance ultra low power Analog-to-Digital

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

control interface and CMOS output data, and is based on a proprietary struc-

ture. Digital error correction is employed to ensure no missing codes in the

complete full scale range.

Two idle modes with fast startup times exist. The entire chip can either be

put in Standby Mode or Power Down mode. The two modes are optimized to

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

consumption during idle mode and startup.

The CDK1307 has a highly linear THA optimized for frequencies up to Nyquist.

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

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