Product Description
Common Frequencies
Contact SaRonix for additional frequencies (see SEL383 for 38 to 212 MHz)
The S1577 is a voltage controlled crystal oscillator that
achieves superb temperature stability over a broad
range of operating conditions and frequencies. The
device is constructed with a hermetically sealed quartz
crystal resonator exhibiting a high-Q for exceptional
performance. The device, available on tape and reel,
is contained in a 7 x 5mm surface mount ceramic
package.

Mechanical Drawings
Please note: In 2005, ceramic package
design changed to allow pin #1 size
decrease as shown. Some older lot codes
may be built with the prior package, in
which case pin #1 is 1.4 x 1.6 mm max.
Recommended Land Pattern*
*External high-frequency power decoupling is
recommended.(see test circuit for minimum recom-
mendation). To ensure optimal performance, do not
route traces beneath the package.
Scale: None. Dimensions are in mm/inches.
