Description
A voltage controlled crystal oscillator de-
signed primarily for use in phase locked
loops, SONET/ATM/SDH/DWDM
transport & switch applications. Output
is 10KE LVPECL. Device is packaged
in a 14-pin DIP compatible, resistance
welded package. Case is grounded to Pin
7 to reduce EMI. True SMD DIL versions
for IR reflow available; select option "S"
or "U" in part builder.
Applications & Features
•
High-frequency, fundamental-mode
crystal design for ultra low jitter and
superb frequency stability over all
conditions
•
Excellent frequency reference for OC-
12 (STM-4), OC-48 (STM-16), and
OC-192(STM-64) clock generation or
synchronization
•
Forward error correction frequencies
are available
•
Enable/Disable standard
Positive supply voltage 3.3V ECL
•
(PECL), LVDS compatible
•
Complementary outputs on S1564
•
Single output on S1562
•
Wide frequency range from
65 MHz to 168.00 MHz
•
±50 ppm minimum APR**
•
Gull Wing & True SMD option available
for IR reflow
•
See S1569 Series for comparable perfor-
mace in true SMD 9x14mm package
•
See S1566 Series for comparable per-
formance with output frequencies 622
~ 670 MHz
