The LTC2262-12 is a sampling 12-bit A/D converter
designedfordigitizinghighfrequency,widedynamicrange
signals.TheLTC2262-12isperfectfordemandingcommu-
nications applications with AC performance that includes
70.5dBSNRand88dBspuriousfreedynamicrange(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.
