The LTC?2175-14/2174-14/2173-14 are 4-channel, simultaneous
sampling 14-bit A/D converters designed for
digitizing high frequency, wide dynamic range signals.
They are perfect for demanding communications applications
with AC performance that includes 73.4dB SNR and
88dB 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 1.2 LSBRMS.
The digital outputs are serial LVDS to minimize the number
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.
