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).
