ACTUAL SIZE
Description
A high performance, low jitter, LVPECL
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 metal package with thru-hole
and true SMD configurations. Case is
grounded to Pin 7 to reduce EMI.
