General Description

The CDK1302 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 750 MSPS. 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 CDK1302’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 CDK1302 operates from a single – 5.2V supply,

with a nominal power dissipation of 5.5W.

The CDK1302 is available in an 80-lead surface-mount MQuad package over

the industrial temperature range (-25°C to +85°C).
