DESCRIPTIO

The LTC

pling 10-bit A/D converters designed for digitizing high

frequency, wide dynamic range signals. The LTC2232/

LTC2233 are perfect for demanding communications

applications with AC performance that includes 61dB SNR

and 75dB spurious free dynamic range for signals

up to 200MHz. Ultralow jitter of 0.15ps

undersampling of IF frequencies with excellent noise

performance.

DC specs include ±0.15LSB INL (typ), ±0.1LSB DNL (typ)

and ±0.8LSB INL, ±0.6LSB DNL over temperature. The

transition noise is a low 0.12LSB

A separate output power supply allows the outputs to drive

0.5V to 3.6V logic.

The ENC

single ended with a sine wave, PECL, LVDS, TTL, or CMOS

inputs. An optional clock duty cycle stabilizer allows high

performance at full speed for a wide range of clock duty

cycles.
