FEATURES

DESCRIPTION

The LTC^®2157-14/LTC2156-14/LTC2155-14 are 2-channel

simultaneous sampling 250Msps/210Msps/170Msps

14-bit A/D converters designed for digitizing high fre-

quency, wide dynamic range signals. They are perfect

for demanding communications applications with AC

performance that includes 70dB SNR and 90dB spurious

freedynamicrange(SFDR). The1.25GHzinputbandwidth

allows the ADC to undersample high frequencies with

good performance. The latency is only five clock cycles.

APPLICATIONS

The digital outputs are double data rate (DDR) LVDS.

–

The ENC and ENC inputs can be driven differentially with

asinewave,PECL,LVDS,TTL,orCMOSinputs.Anoptional

clock duty cycle stabilizer allows high performance at full

speed for a wide range of clock duty cycles.
