ICST ICS3727XP
The ICS3727XP combines the functions of a VCXO (Voltage Controlled Crystal Oscillator) and PLL (Phase-Locked Loop) frequency doubler onto a single chip. It is designed primarily for data and clock recovery applications within end products such as set-top box receivers. The ICS3727XP exhibits a moderate VCXO gain of 200 ppm/V typical, when used with a high quality external pullable quartz crystal.| Part No. | ICS3727XP |

DESCRIPTION
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.FEATURES
● ICS3727XP offers 24 to 36 MHz output frequency range (output frequency = 2x crystal frequency) and improved power supply noise rejection● Uses an inexpensive 12 to 18 MHz external crystal
