004 13 July 2006 MAS9278 IC for 10.
00 – 30.
00 MHz VCXO • • • • • • • • DESCRIPTION The MAS9278 is an integrated circuit well suited to build VCXO for mobile communication.
The crystal offset trimming is done through a serial bus and the calibration information is stored in an internal PROM.
To build a VCXO only one additional component, a crystal, is needed.
