CDCEL925PW

The CDCEL925PW is a highly integrated clockand timing solution that creates multiple customized 3.3V output frequency solutions, eliminating the need for external clockgenerator components in many applications. This versatile devicenot only provides low-cost solutions, but also reduces the needfor clock level shifting. However, the application field and workingprinciple of the CDCEL925PW is still a mystery for many. In thisarticle, we will go into the details of the CDCEL925PW and seewhat it does and what it can do for you.

The CDCEL925PW is designed to be used as a clocksynthesizer, PLL, and frequency synthesizer. It offers a highlyintegrated solution with low cost and low EMI, while providing asimplified and more cost-effective approach to architecture anddesign requirements. The CDCEL925PW is capable of synthesizingmultiple clock frequencies in one device, so it is capable ofcreating frequencies that are at the same frequency and atdifferent frequencies. This allows users to create the rightfrequency for their application without having to use additionalexternal devices.

The CDCEL925PW can be used in a variety ofapplications. It is primarily used in the telecommunicationsindustry, where it can help provide frequency, timing, andamplitude modulation required for fixed-rate telecom, as well asburst-mode applications like satellite, cellular, and IPcommunications. In the industrial and instrumentation industry,the CDCEL925PW can be used for controlling the frequency ofoscillators, function generators, and other timing devices. Inaddition, it can be used for generating accurate clock pulsesneeded for data acquisition, image processing, and otherapplications requiring precise timing.

The CDCEL925PW works via a phase-locked loop(PLL) circuit. This circuit is able to generate an outputfrequency that is locked to an input reference frequency, whilestill being adjustable. The PLL works by using two separateoscillators, one as the reference frequency (Ref-Clk), and oneas the feedback oscillator (F-Clk). The two signals are input intothe PLL, and it then compares the phases between the two. Ifthe phases are not equal, it then adjusts the feedback oscillatorfrequency until the phases are the same, at which point the outputfrequency is locked to the reference frequency. This allows theoutput frequency to be adjusted to the desired target frequencywith minimal noise and jitter.

The CDCEL925PW also features a wide variety of features tohelp reduce EMI and clock jitter. It offers both high-bandwidthand low-bandwidth frequency synthesis modes, allowing the userto adjust the bandwidth as needed to reduce EMI. It alsofeatures an integrated programmable filter that offers low-pass andhigh-pass filtering options, along with additional signalprocessing options. This helps minimize EMI and jitter, while stillallowing for accurate outputs.

The CDCEL925PW is a powerful and versatile clock and timingsolution. It can help reduce component costs, reduce EMI, andprovide precise timing for a variety of applications. It is one ofthe few integrated solutions on the market that can be used togenerate multiple clock frequencies in one device. With thisversatility and power, it is no wonder why the CDCEL925PW isbecoming a popular choice for clock and timing applications.
