DS-195 REV B
Voltage Controlled Crystal Oscillator
Technical Data
SaRonix
S1554 Series
5V PECL
Frequency Range:
70 MHz to 155.52 MHz

shock and vibration.
ACTUAL SIZE
Description
A voltage controlled 5V PECL crystal
oscillator designed primarily for use in
phase locked loops, Sonet, ATM, SDH
and Network/Switch applications.
Complementary outputs are Motorola
10KE compatible and can be enabled/
disabled. Device is packaged in a 14-pin
DIP compatible, resistance welded pack-
age with case grounded to Pin 7 to reduce
EMI. True SMD DIL versions for IR
reflow are available, select option "S" or
"U" in part number builder. See separate
data sheet for SMD package dimensions
