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