ICS726

www.DataSheet4U.com ICS726 12 TO 36 MHZ SOT-23 VCXO Description Used in conjunction with an external pullable quartz crystal, this monolithic integrated circuit replaces more costly hybrid (canned) VCXO devices. The ICS726 is designed primarily for data and clock recovery applications such as ADSL modems, set-top box receivers, and telecom systems. The frequency of the on-chip VCXO is adjusted by an external control voltage to the VIN pin. Since VIN is a high impedance input, it can be driven directly from an PWM RC integrator circuit. Frequency output increases with VIN voltage input. The usable range of VIN is 0 to 3.3 V. Features Uses an inexpensive 12 to 36 MHz external crystal Output frequency range of 12 to 36 MHz On-chip VCXO with guaranteed pull range of ±115 ppm minimum VCXO tuning voltage 0 to 3.3 V Packaged in 6-pin TSOT-23-6 Available in Pb (lead) free package Block Diagram VDD DataShee DataSheet4U.com VIN X1 12-36MHz Pullable Crystal X2 Voltage Controlled Crystal Oscillator 12-36MHz GND DataSheet4U.com MDS 726 F I n t e gra te d C i r c u i t S y s t e m s ● 1 525 Race Stre et, San Jo se, CA 9 5126 ● Revision 112905 te l (40 8) 2 97-12 01 ● w w w. i c st . c o m DataSheet4 U .com www.DataSheet4U.com ICS726 12 TO 36 MHZ SOT-23 VCXO Pin Assignment X2 GND CLK 1 2 3 6 5 4 X1 VI N VDD T S OT - 2 3 - 6 Pin Descriptions Pin Number 1 2 3 4 5 6 Pin Name X2 GND CLK VDD VIN XI Pin Type Input Power Output Power Input Input Connect to ground...
