DESCRIPTION
The LTC®2265-14/LTC2264-14/LTC2263-14 are 2-channel,
simultaneous sampling 14-bit A/D converters designed
for digitizing high frequency, wide dynamic range signals.
They are perfect for demanding communications applica-
tions with AC performance that includes 73.7dB SNR and
90dB spurious free dynamic range (SFDR). Ultralow jitter
of 0.15psRMS allows undersampling of IF frequencies with
excellent noise performance.
DC specs include ±1LSB INL (typ), ±0.3LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 1.2LSBRMS.
The digital outputs are serial LVDS to minimize the num-
ber of data lines. Each channel outputs two bits at a time
(2-lane mode) or one bit at a time (1-lane mode). The LVDS
drivers have optional internal termination and adjustable
output levels to ensure clean signal integrity.
The ENC+ and ENCinputs may be driven differentially
or single-ended with a sine wave, PECL, LVDS, TTL, or
CMOS inputs. An internal clock duty cycle stabilizer
allows high performance at full speed for a wide range of
clock duty cycles.
