TYPICAL APPLICATION
DESCRIPTION
16-Bit, 65Msps/40Msps/
25Msps Low Power
Dual ADCs
The LTC2192/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
0.07psRMS allows undersampling of IF frequencies with
excellent noise performance.
DC specs include ±2LSB INL (typ), ±0.5LSB DNL (typ)
and no missing codes over temperature. The transition
noise is 3.3LSBRMS.
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.
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.
