Description
A high performance, low jitter, PECL
voltage controlled crystal oscillator, de-
signed primarily for use in phase locked
loops, Sonet, ATM and SDH network/
switching applications. Complementary
outputs are Motorola 10KE compatible
and can be enabled/disabled. Device is
packaged in a 14-pin DIP compatible,
hermetic package. Case is grounded to
Pin 7 to reduce EMI.
Applications & Features
Positive supply voltage - 5V PECL
Output Enable/Disable feature
Complementary Output
High frequency 622.08 MHz using
SaRonix' proprietary fundamental crys-
tals for exceptional jitter performance
