ICS726 Datasheet | Integrated Circuit Systems

.. 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 tele 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 -...
