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.
