TCVCXO Oscillator
November 2012
•Pletronics
TCG4 Series is an precision temperature
compensated crystal oscillator.
•The
TCG4 has a clipped-sine output.
•Frequencies
available from 15MHz to 52 MHZ
•Supply
voltages from 1.8V to 3.3V
•1.6
X 2.0 mm Ceramic LCC Package
•Very
Low Power consumption
•Optional
Voltage Control function
•Low
phase noise and jitter
Mechanical:
NC= no external connection allowed
Contacts: gold 11.8 to 39.4 -inches (0.3 to 1.0 m) over
Nickel 50 to 350 -inches (1.27 to 8.89 m).
Layout and Application Information
For optimum jitter performance, Pletronics recommends:
•
A ground plane under the device
•
•
•
No large transient signals (both voltage and current) should
be routed under the device.
Do not layout near large magnetic fields such as high fre-
quency switching power supplies.
Do not place near piezoelectric buzzers or mechanical fans.
Product information is current as of publication date. The product conforms
to specifications per the terms of the Pletronics standard warranty. Production
processing does not necessarily include testing of all parameters.
