5P49EE502NDGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The 5P49EE502NDGI8 is a VersaClock low power programmable clock generator manufactured by Renesas Electronics. It features four internal PLLs capable of generating up to five independent output frequencies from a single reference clock, supporting input frequencies from 8 MHz to 40 MHz and output ranges from kHz to 120 MHz. The device operates on a 1.71V to 3.465V supply with I/O standards including 1.8V/2.5V/3.3V LVTTL/LVCMOS. It integrates an internal non-volatile EEPROM for configuration storage and supports FAST mode (400kHz) I2C serial interfaces. Packaged in a 20-VFQFN (3x3mm) exposed pad, it is designed for battery-operated consumer applications.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'NDGI8' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required I2C address settings and voltage levels before procurement. Check for any recent Product Change Notifications (PCN) regarding material or assembly changes.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when designing for low power consumer electronics requiring up to five distinct clock frequencies. Verify that the 1.71V to 3.465V core voltage range aligns with the system power budget. Confirm that the 20-VFQFN package dimensions fit the PCB layout constraints and that the thermal requirements for the exposed pad are met.

Clock Generators, PLLs, Frequency Synthesizers Part Context
