The LTC2258-12/LTC2257-12/LTC2256-12 are sam-

pling 12-bit A/D converters designed for digitizing high

frequency, wide dynamic range signals. They are perfect

for demanding communications applications with AC

performancethatincludes71.1dBSNRand88dBspurious

free dynamic range (SFDR). Ultralow jitter of 0.17psRMS

allows undersampling of IF frequencies with excellent

noise performance.

DC specs include ±0.3LSB INL (typical), ±0.1LSB DNL

(typical) and no missing codes over temperature. The

transition noise is a low 0.3LSBRMS.

The digital outputs can be either full rate CMOS, double

data rate CMOS, or double data rate LVDS. A separate

output power supply allows the CMOS output swing to

range from 1.2V to 1.8V.

The ENC+ and ENC– inputs may be driven differentially

or single-ended with a sine wave, PECL, LVDS, TTL or

CMOS inputs. An optional clock duty cycle stabilizer al-

lows high performance at full speed for a wide range of

clock duty cycles.
