1 / 9 page  DA9270.008 11 September 2006 1 (9) MAS9270 IC FOR 10.00 – 30.00 MHz VCTCXO • Wide Supply Voltage Range • True Sine Wave Output • Very High Level of Integration • Electrically Trimmable • Very Low Phase Noise • Low Cost • Minimum Operating Temperature –40 °C 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 APPLICATIONS • 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 • VCTCXO for mobile phones • VCTCXO for other telecommunications systems BLOCK DIAGRAM T Vref TMux Σ DA CLK PV VSS VC VDD 4 4 f(T) f(T) 4 8 CUB INF SENS LIN 8 CDAC1 CDAC2 TE1 TE2 X2 OUT X1 2 MAS9270 |
