5V49EE902-252NLGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The 5V49EE902-252NLGI is a programmable clock generator from the VersaClock III family, manufactured by Renesas Electronics. It features four internal PLLs and an internal non-volatile EEPROM for configuration storage. The device supports input frequencies from 1 MHz to 200 MHz and generates output frequencies up to 500 MHz. It operates on a 3.3 V core supply and includes I2C serial interface programming with fast mode support at 400 kHz. The component is housed in a VFQFPN-32 package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The 5V49EE902-252NLGI belongs to the VersaClock III series of EEPROM programmable clock generators. This series is designed for applications requiring multiple clock outputs derived from a single reference source. The suffix 'NLGI' indicates the specific tape-and-reel packaging and temperature grade variant within the broader 5V49EE902 product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public documentation lists the 5P35021 and 5P35023 as alternative products within the VersaClock 3S family. These devices offer similar programmable clock generation capabilities but may differ in pinout, feature set, or performance specifications. Verification against the original design requirements is necessary before substitution.
