FEATURES

DESCRIPTION

The LTC^®2192/LTC2191/LTC2190 are 2-channel, simul-

taneous sampling 16-bit A/D converters designed for

digitizinghighfrequency,widedynamicrangesignals.They

are perfect for demanding communications applications

with AC performance that includes 77dB SNR and 90dB

spurious free dynamic range (SFDR). Ultralow jitter of

RMS

To minimize the number of data lines the digital outputs

are serial LVDS. Each channel outputs one bit, two bits or

four bits at a time. The LVDS drivers have optional internal

termination and adjustable output levels to ensure clean

signal integrity.

APPLICATIONS

Communications

Cellular Base Stations

–

Software-Deﬁned Radios

Portable Medical Imaging

Multi-Channel Data Acquisition

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 allows high

performance at full speed for a wide range of clock duty

cycles.
