TYPICAL APPLICATION
DESCRIPTION
14-Bit, 65Msps/40Msps/
25Msps Low Power Dual ADCs
TheLTC2265-14/LTC2264-14/LTC2263-14are2-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 0.15psRMSallowsundersamplingofIFfrequencieswith
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 ENC– inputs 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.
