LOW COST 27 MHZ VOLT VCXO DATASHEET ICS722 The ICS722 is a low cost, low-jitter, high-performance volt VCXO designed to replace expensive discrete VCXOs modules. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to V input voltage to cause the output clocks to vary by over ±100 ppm. Using IDT’s patented VCXO techniques, the device uses an inexpensive external pullable crystal in the range of to 28 MHz to produce a VCXO output clock at that same frequency. The frequency of the on-chip VCXO is adjusted by an external control voltage input into pin VIN. Because 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 V. IDT manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications.

LOW COST 27 MHZ VOLT VCXO

DATASHEET

ICS722

The ICS722 is a low cost, low-jitter, high-performance volt VCXO designed to replace expensive discrete VCXOs modules. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to V input voltage to cause the output clocks to vary by over ±100 ppm. Using IDT’s patented VCXO techniques, the device uses an inexpensive external pullable crystal in the range of to 28 MHz to produce a VCXO output clock at that same frequency.

The frequency of the on-chip VCXO is adjusted by an external control voltage input into pin VIN. Because 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 V.

IDT manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. Consult IDT to eliminate VCXOs, crystals, and oscillators from your board.
