mas9276
Description
Ic For 10.00 ? 30.00 Mhz Vctcxo
Manufacturer
Micro Analog Systems Oy
Datasheet
DESCRIPTION
MAS9276 is integrated circuit well suited to build
VCTCXO for mobile communications. Temperature

temperatures only. The trimming is done through a
serial bus and the calibration information is stored
in an internal PROM. This means that no rework
for trimming is needed.

APPLICATIONS
To build a VCTCXO only a crystal is required in
addition to MAS9276. The compensation method
is fully analog, working continuously without
generating any steps or other interference.
