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

free dynamic range (SFDR). The 1.25GHz input bandwidth

allows the ADC to undersample high frequencies with

good performance. The latency is only five clock cycles.

DC specs include ±0.85LSB INL (typ), ±0.25LSB DNL (typ)

and no missing codes over temperature. The transition

noise is 1.82LSBRMS.

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

The ENC+ and ENC– inputs can be driven differentially with

a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional

clock duty cycle stabilizer allows high performance at full

speed for a wide range of clock duty cycles.
