MAS9279

Manufacturer Part Number
MAS9279
Description
IC FOR 10.00 - 52.00 MHz VCTCXO
Manufacturer
MAS
Datasheet
DESCRIPTION
The MAS9279 is an integrated circuit well suited to
build high end VCTCXO for telecommunication.
The trimming is done through a serial bus and the
calibration information is stored in an internal
PROM. This means no rework for trimming is
needed.

APPLICATIONS
Vref
To build a VCTCXO only crystal is required in
addition to MAS9279. The compensation method is
fully
generating any steps or other interference.
