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
