PECL
www.pericom.com/saronix
Frequency Range: 38.88 MHz to 155.52 MHz
Frequency Stability: ±20, ±25, ±50, or ±100 ppm over all conditions: operating
temperature, supply voltage change, load change, calibration
tolerance, shock and vibration.
ACTUAL SIZE
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.
Applications & Features
Positive supply voltage ECL (PECL)
Complementary outputs
Wide frequency range from 38.88 MHz
to 155.52 MHz using SaRonix funda-
mental crystals for exceptional jitter
performance
±50 or ±100 ppm minimum APR*
Covers wide range of telecommunica-
tion applications
Other features such as enable/disable
and negative supply are available in
this series, consult factory
