DESCRIPTIO

The LTC

verter designed for digitizing high frequency, wide dy-

namic range signals. The LTC2234 is perfect for demand-

ing communications applications with AC performance

that includes 60.5dB SNR and 75dB spurious free dy-

namic range for signals up to 400MHz. Ultralow jitter of

0.15ps

excellent noise performance.

DC specs include ±0.2LSB 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 CMOS output

swing to range from 0.5V to 3.6V.

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.
