ICS91857AG Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The ICS91857AG is a Clock/Timing generator, known as a Phase Lock Loop (PLL) frequency synthesizer, manufactured by Integrated Circuit Systems, Inc. It is a premium-quality programmable frequency generator, suitable for a wide range of applications, making it one of the most popular generators on the market.The ICS91857AG is a versatile programmable frequency generator that can generate frequencies from Crystal/RTC oscillator signals from 8 kHz to 800 MHz. It can also be used to control the frequency and timing of multiple functions in a single application, making it ideal for a variety of digital and analog systems.The ICS91857AG works by applying a signal at a specific frequency to an input which it then modulates the frequency of the generated signal with the input signal. This is done using a PLL circuit, which is essentially a Frequency Detection Circuit that monitors the incoming signal and adjusts the output signal’s frequency accordingly. This process creates an output signal which is an exact multiple of the input signal’s frequency.The ICS91857AG also has several output options. The outputs can range from two to four channels, TDM (Time Domain Mechanism) or parallel, and can be run in either synchronous or asynchronous mode. Synchronous mode produces a single, stable frequency from its output. Asynchronous mode produces multiple frequencies that are modulated together to create the desired frequency output. The ICS91857AG also has the ability to adjust output amplitude and frequency.The ICS91857AG can be used for a variety of applications including cellular base station, wireless networking, audio/video systems, military, and instrumentation. Because of its flexible design, it can also be used in any application where an accurate and reliable frequency is needed.In addition to being versatile and easy to use, the ICS91857AG is compact and highly reliable. It has been built with the latest circuitry and components ensuring reliable frequency generation and high accuracy and has been tested under extreme conditions to ensure quality performance. The ICS91857AG is also certified to be RoHS compliant, meaning that it is safe to use in any environment.The ICS91857AG is the perfect solution for any application requiring a programmable clock and timing generator. Its versatile design and reliable performance makes it the ideal choice for a wide range of systems and applications.
