Data Sheet 0748E
For use with High Bandwidth
analog-to-digital converters (ADC)
and digital-to-analog converters (DAC)
Description
The AP-XX57XXX-X Series
of crystal oscillators (XO) provides high frequency
multiple synchronous clocks, including AC coupled high slew rate square-wave (or sine-wave)
differential pair for ADC/DAC; differential PECL; and LVDS outputs. Logic outputs can be referenced
to 2 different supply voltages. The device provides exceptionally low Phase Noise and Jitter.

Outline tolerance: ±0.015”/0.4mm (unless otherwise specified
Notes:
* This spec is preliminary and could be addressed on the case by case basis. Since different ADC/DAC have different
requirements and different input impedances – this spec along with output impedance on QH/QHN would vary for
particular custom requirement.
** Usually, to achieve frequency higher than 250 MHz Low Noise analog multiplication technique is used. As a rule the
multiplication factor is odd number. If the frequency of sub-harmonic and its multiples is important for the application,
customer is encouraged to specify multiplication factor for F > 250 MHz.
