The LTC
2232 and LTC2233 are 105Msps/80Msps, sam-
pling 10-bit A/D converters designed for digitizing high
frequency, wide dynamic range signals. The LTC2232/
LTC2233 are perfect for demanding communications
applications with AC performance that includes 61dB SNR
and 75dB spurious free dynamic range for signals
up to 200MHz. Ultralow jitter of 0.15psRMS allows
undersampling of IF frequencies with excellent noise
performance.
DC specs include
±0.15LSB INL (typ), ±0.1LSB DNL (typ)
and
±0.8LSB INL, ±0.6LSB DNL over temperature. The
transition noise is a low 0.12LSBRMS.
A separate output power supply allows the outputs to drive
0.5V to 3.6V logic.
The ENC+ and ENCinputs may be driven differentially or
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.
