The ICS275PGIT is a clock/timing device used for a wide range of industrial, consumer and telecommunications applications. It is a highly integrated, single-chip CMOS clock generator, phase-locked loop (PLL) and frequency synthesizer. It is designed to provide a low-cost and cost-effective solution for applications that require a system clock, such as TV and monitor sync, communication systems, HDD controllers, embedded systems and other applications.

The ICS275PGIT has an integrated oscillator, phase-locked loop (PLL) and the output frequency synthesizer. The on-chip oscillator can generate a fixed frequency of 27.000MHz that is used as a reference frequency. It has an unlimited frequency range of 10kHz-275MHz and has a resolution of 10kHz-10MHz, respectively. The PLL has a reference input and can operate in three modes: VCO (variable frequency), RCO (reset frequency) and MCO (manual frequency). The output frequency synthesizer can be used to convert the reference frequency to any desired frequency within the range.

The ICS275PGIT has a wide range of features including: output frequency adjustment, power management, programmable time-out, synchronization output and a calibration circuit. The output frequency adjustment can be used to adjust the output frequency from 10kHz to 275MHz over a range of 5.5 to 1.5V. The power management feature can be used for controlling the clock supply voltage. The programmable time-out feature is used to enable the chip to enter into the power saving mode after a programmable length of time. The synchronization output feature can be used to synchronize the generated clock signals with external clock signals. The calibration circuit is used to calibrate and stabilize the output frequency if the reference frequency is not within the specified range.

The ICS275PGIT is a very versatile clock/timing device and can be used in a wide range of applications such as TV and monitor synchronization, communication systems, HDD controllers, embedded systems and other applications. It has a low power consumption and high performance. Moreover, it has an unlimited range of frequency synthesis and is an inexpensive solution for the mentioned applications.
