5V49EE904-074NLGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas Electronics 5V49EE904-074NLGI is an EEPROM programmable clock generator belonging to the VersaClock III series. It features four internal phase-locked loops (PLLs) capable of generating up to nine output clocks from a single reference source. The device supports input frequencies ranging from 1 MHz to 200 MHz and output frequencies up to 200 MHz. Key specifications include a maximum jitter of 80 ps, operation within a -40°C to +85°C industrial temperature range, and a 3.3 V core supply voltage. The component is housed in a 32-pin VFQFPN package with surface-mount installation.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix '074' against official Renesas documentation to confirm pinout, packaging, or electrical variations compared to the standard 5V49EE904NLGI. Confirm current production status as related variants may be discontinued. Ensure compatibility with existing I2C addressing and power supply requirements before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when multiple distinct clock frequencies are required from a single reference source. The integrated EEPROM simplifies design by eliminating external configuration memory. Verify that the 200 MHz maximum output frequency meets system requirements and that the 80 ps jitter specification satisfies signal integrity constraints for the target application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Renesas VersaClock III family, designed for flexible clock distribution. The 5V49EE904 variant specifically offers nine outputs, distinguishing it from lower-output models like the 5V49EE902. The device integrates spread spectrum generation on two PLLs to assist in electromagnetic interference reduction.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Officially documented substitutes for the base 5V49EE904 model include the 5P35023B-000. Verify if the 5P35023B-000NLGI variant matches the specific electrical and package requirements of the 5V49EE904-074NLGI.
