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.

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.
