Description
A voltage controlled PECL crystal oscil-
lator designed primarily for use in phase
locked loops, Sonet, 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.
