www.DataSheet4U.com DA9275.007 19 February 2004 MAS9275 IC FOR 10.00 – 36.00 MHz VCXO DESCRIPTION MAS9275 is a VCXO IC to be used in making VCXO modules for telecommunication and other applications. To build a complete VCXO only one additional component, a crystal, is needed. Square Wave (CMOS) Output Very Low Phase Noise Low Power Wide Supply Voltage Range Very High Level of Integration Low Cost FEATURES Very small size Minimal current consumption Wide operating temperature range Phase noise <-130 dBc/Hz at 1 kHz offset Square wave (CMOS) output APPLICATIONS VCXO for telecommunications systems VCXO for set-top boxes VCXO for MPEG BLOCK DIAGRAM PD VC OUT MAS9275 VDD VSS X1 X'Tal X2 1 (10) DA9275.007 19 February 2004 PIN DESCRIPTION Pin Description Crystal/Varactor Oscillator Input Voltage Control Input Power Supply Ground Buffer Output Power Supply Voltage Tri State Crystal Oscillator Output Symbol X1 VC VSS OUT VDD PD X2 x-coordinate 209 425 600 1029 841 379 197 y-coordinate 161 165 175 1030 1016 1028 1030 Note Note: Because the substrate of the die is internally connected to GND, the die has to be connected to GND or left floating. Please make sure that GND is the first pad to be bonded. Pick-and-place and all component assembly are recommended to be performed in ESD protected area. Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The coordinates may vary depending on sawing widt...
