DescripTion

TheLTC^®2175-14/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

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.
