1 / 6 page  MDS 722 A 1 Revision 121404 Integrat ed Circuit Systems ● 525 Race Stre et, San Jo se, CA 9 5126 ● te l (40 8 ) 2 97-12 01 ● www.ics t.co m LOW COST 27 MHZ 3.3 VOLT VCXO ICS722 Description The ICS722 is a low cost, low-jitter, high-performance 3.3 volt VCXO designed to replace expensive discrete VCXOs modules. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3 V input voltage to cause the output clocks to vary by over ±100 ppm. Using ICS’ patented VCXO techniques, the device uses an inexpensive external pullable crystal in the range of 16.2 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 3.3 V. ICS manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. Consult ICS to eliminate VCXOs, crystals, and oscillators from your board. Features • Packaged in 8-pin SOIC • Operational frequency range of 16.2 MHz to 28 MHz • Uses an inexpensive external crystal • On-chip patented VCXO with pull range of 230 ppm (minimum) • VCXO tuning voltage of 0 to 3.3 V • Operating voltage of 3.3 V • 12 mA output drive capability at TTL levels • Advanced, low-power, sub-micron CMOS process Block Diagram X1 X2 Voltage Controlled Crystal Oscillator VIN 16.2-28MHz Pullable Crystal 16.2-28MHz Clock (REFOUT) GND VDD |
