Working Principles

The CDCEL913IPWRQ1 is a clock generator and jitter cleaner IC that generates high-frequency clock signals with low jitter. It utilizes an internal phase-locked loop (PLL) to multiply or divide the input clock frequency, providing precise timing for various electronic devices.

The device can accept an external clock input or use an external crystal oscillator as the reference. The PLL then locks onto this reference signal and generates multiple output clocks with programmable frequencies and phases. These output clocks can be in LVCMOS, LVDS, or LVPECL format, depending on the application requirements.

The CDCEL913IPWRQ1 also features an I2C serial interface, allowing users to configure and control the device easily. This interface enables programming of the PLL multiplication/division factors, output formats, and other parameters.

Detailed Application Field Plans

The CDCEL913IPWRQ1 is widely used in various electronic systems that require precise clock signals. Some common application fields include: - Telecommunications equipment - Networking devices - Data storage systems - Test and measurement instruments - Industrial automation systems - Consumer electronics
