Product Description
The S3T01 series is a temperature compensated crystal
oscillator with optional voltage control function that
achieves Stratum 3 holdover and lifetime performance.
The device is constructed with a hermetically sealed
crystal oscillator and a temperature compensation
circuit mounted on a 9x14mm FR4 base and covered
with an RFI-shielded metal lid. The device is available
on tape and reel for automated pick-and-place
assembly.

Phase Noise
Notes:
1. Relative to the specified nominal frequency (FN), measured at RMT within 24 hours after first assembly reflow and control voltage held at center (if applicable).
2. Relative to the specified nominal frequency (FN), includes frequency deviation due to: operating temperature changes, rated input (supply) voltage changes, load
changes, calibration tolerance, aging (20 years at 40°C average ambient operating temperature), shock and vibration.
3. Versus temperature and drift. Relative to frequency at RMT
4. Total. Peak-to-peak absolute deviation between +10°C and +50°C in 24 hours with 2°C min-1 max slew rate; all other conditions as per GR-1244-CORE.

Recommended Land Pattern*
The S3T01 product has six (6)
contact pads located along opposite
sides to be connected as per the pin
function definitions. An additional
four (4) pads, located along op-
posite ends, are used for factory
programming only; do not connect
these pads.
*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.
