TheLTC2175-14/LTC2174-14/LTC2173-14are4-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 73.1dB SNR and
88dB 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). At lower sampling rates there is a one bit
per channel option (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 al-
lows high performance at full speed for a wide range of
clock duty cycles.
