1 / 9 page  1 (9) DA1175.008 13 July, 2006 MAS1175 IC FOR 10.00 – 20.00 MHz VCTCXO • Low Power • Wide Supply Voltage Range • True Sine Wave Output • Very High Level of Integration • Electrically Trimmable • Very Low Phase Noise • Low Cost DESCRIPTION The MAS1175 is an integrated circuit well suited to build VCTCXO for mobile communication. Only two external components are needed. Temperature calibration is achieved with three calibration points only. The trimming is done through a serial bus and the calibration information is stored in an internal PROM. To build a VCTCXO only two additional components, a varactor and a crystal are needed. The compensation method is fully analog. IC compensation work is continuous without generating any steps or other interferences. FEATURES APPLICATIONS • Very small size • Minimum current draw • Wide operating temperature range • Phase noise <-130 dBc/Hz at 1 kHz offset • VCTCXO for mobile phones • VCTCXO for other telecommunications systems BLOCK DIAGRAM MAS1175 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 |
