Additional Details

The 9LPRS489CGLFT typically operates from a 3.3V power supply and is available in a lead-free package. Configuration and control are achieved via an I2C or SMBus interface, allowing the host system to program the output frequencies and other relevant parameters. The integrated PLL enables the chip to multiply the input reference clock to generate a wide range of output frequencies. Detailed electrical characteristics, timing specifications, and programming interfaces can be found in the official datasheets and application notes provided by Renesas Electronics.

This clock synthesizer is essential for maintaining the proper timing and synchronization required for optimal performance in advanced electronic systems.
