DESCRIPTION
The MAS9270 is an integrated circuit well suited to build VCTCXO for mobile communication. Temperature calibration is achieved in three calibration temperatures only. 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. To build a VCTCXO additionally only crystal is required. The compensation method is fully analog, working continuously without generating any steps or other interference.

FEATURES
• Very small size
• Minor current draw
• Wide operating temperature range
• Phase noise <-120 dBc/Hz at 100Hz offset
• Programmable VC-sensitivity
• Minimum Operating Temperature –40 °C for MAS9270Cxx3

APPLICATIONS
• VCTCXO for mobile phones
• VCTCXO for other telecommunications systems
