converters designed for digitizing high frequency, wide
dynamic range signals. They are perfect for demanding
communications applications with AC performance that
includes 76.8dB SNR and 90dB spurious free dynamic
range (SFDR). Ultralow jitter of 0.07ps
RMS
allows unders-
ampling 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 3.4LSB
RMS
.
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.
