MAS9276
IC for 10.00 â 30.00 MHz VCTCXO
DESCRIPTION
MAS9276 is integrated circuit well suited to build
VCTCXO for mobile communications. Temperature
calibration is achieved at three calibration
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.
FEATURES
⢠Very small size
⢠Minimal current consumption
⢠Wide operating temperature range
⢠Phase noise <-120 dBc/Hz at 100 Hz offset
⢠Programmable Vc sensitivity
BLOCK DIAGRAM
⢠Very High Control Voltage
Sensitivity
⢠True Sinewave Output
⢠Electrically Trimmable
⢠Very Low Phase Noise
⢠Low Power
⢠Low Cost
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.
APPLICATIONS
⢠VCTCXO for mobile phones
⢠VCTCXO for other telecommunications
systems
