Description
A voltage controlled crystal oscillator
designed primarily for use in phase locked
loops, Sonet, ATM, SDH and network/
switch applications. Output is LVPECL
and Motorola 10KE compatible. Device
is packaged in a 14-pin DIP compatible,
resistance welded package. Case is
grounded to Pin 7 to reduce EMI.
