frequency, wide dynamic range signals. They are perfect
for demanding communications applications with AC
performance that includes 73.4dB SNR and 85dB spurious
free dynamic range (SFDR). Ultralow jitter of 0.17psRMS
allows undersampling of IF frequencies with excellent
noise specs include ±1LSB INL (typical), ±0.3LSB DNL (typi-cal) and no missing codes over temperature. The transition
noise is a low 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 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 allows high
performance at full speed for a wide range of clock duty
cycles.L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear
