General Description
The CDK1303 is a full parallel (flash) analog-to-digital converter capable
of digitizing full scale (0 to -2V) inputs into eight-bit digital words at an
update rate of 1 GSPS. The ECL-compatible outputs are demultiplexed into
two separate output banks, each with differential data ready outputs to ease
the task of data capture. The CDK1303’s wide input bandwidth and low
capacitance eliminate the need for external track-and-hold amplifiers for most
applications. A proprietary decoding scheme reduces metastable errors to the
1 LSB level. The CDK1303 operates from a single -5.2V supply, with a nominal
power dissipation of 5.5W.
The CDK1303 is available in an 80-lead surface-mount MQUAD package over
the industrial temperature range (-25°C to +85°C).
