The ICS93V855AG Clock/Timing - Application Specific device is a high performance, fully differential fractional-N synthesizer designed to provide precise frequency control in modern communication, networking, and embedded systems. It supports frequent frequency changes in a range from 0.128GHz to 125MHz in precisely controlled steps for a precision of up to 0.1ppm.

This fractional-N synthesizer achieves high accuracy and stability by combining a finely-tunable voltage-controlled oscillator (VCO), a phase-locked loop (PLL), a digital signal processor (DSP), and advanced cellular calibration techniques to calculate and adjust the accurate frequency setting. Different frequency ranges and dividers allow the VCO output frequency to be easily tailored to a desired application.

The ICS93V855AG can be used as a Programmable Clock Oscillator to reduce the design time and cost associated with the vco tuning and verification. It can also be used as a Frequency Translator and Divider, making it an ideal solution for applications with stringent requirements for precise timing control.

The device features two programmable IC based VCOs with numeral dividers for precise frequency control. The VCO output frequency can be programmed between 0.128GHz and 125MHz, with a resolution of 0.1ppm for up to five decimal places. The VCOs also feature a low core noise and a flat frequency response for consistent, reliable output. Additionally, with an analog output, the ICS93V855AG can be tuned to match the output frequency of any system.

In addition to the VCOs and dividers, the ICS93V855AG includes on-chip programmable Doppler shaping circuits, automatically compensating for frequency deviations caused by temperature variations, supply voltage, and unavoidable fabrication process variations. Additional features include a 12-bit serial interface, pulse width modulation and spread spectrum modulation for radio frequency endpoint applications, and a Self-Exclusion Circuit which can be used to avoid interference among multiple units.

The ICS93V855AG is designed for use in highly-integrated and frequency-sensitive, low-power applications. As an example, it is well suited for use in wireless communications networks, industrial control systems, avionics, test and measurement instruments, and medical systems where precise and stable frequency control is required.

Overall, the ICS93V855AG Clock/Timing - Application Specific device is an advanced, low power, and highly-integrated solution that offers extraordinary precision and stability for a wide range of frequency-sensitive applications.
