TheLTC2172-14/LTC2171-14/LTC2170-14are4-channel,
simultaneoussampling14-bitA/Dconvertersdesignedfor
digitizinghighfrequency,widedynamicrangesignals.They
are perfect for demanding communications applications
with AC performance that includes 73.7dB SNR and 90dB
spurious free dynamic range (SFDR). An ultralow jitter of
0.15psRMS allows undersampling of IF frequencies with
excellent noise performance.
DC specifications include ±1LSB INL (typ), ±0.3LSB DNL
(typ) and no missing codes over temperature. The transi-
tion 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 al-
lows high performance at full speed for a wide range of
clock duty cycles.
