LTC2194/LTC2193
16-Bit, 125/105/80Msps
Low Power Dual ADCs
DESCRIPTION
The LTC®2195/LTC2194/LTC2193 are 2-channel, simul-
taneous sampling 16-bit A/D converters designed for
digitizing high frequency, wide dynamic range signals.
They are perfect for demanding communications applica-
tions with AC performance that includes 76.8dB 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 3.4LSBRMS.
To minimize the number of data lines the digital outputs
are serial LVDS. Each channel outputs two bits or four bits
at a time. At lower sampling rates there is a one bit per
channel option. The LVDS drivers have optional internal
termination and adjustable output levels to ensure clean
signal integrity.
The ENC+ and ENCinputs 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.
