Pin selectable input ranges of ±1V and ±1.6V along with a resistor programmable mode allow Ultralow jitter of 0.15psRMS allows undersampling of IF frequencies with excellent noise performance. DC specs include ±1.5 LSB INL and ±0.8LSB DNL over temperature. The ENC and ENC inputs may be driven differentially from PECL, GTL and other low swing logic families or from single-ended TTL or CMOS.
