IDT, Integrated Device Technology Inc 5V49EE902NLGI

Description
The IDT5V49EE902 is a programmable clock generator designed for highperformance data communications, telecommunications, consumer, and networking applications. It features four internal PLLs, each individually programmable, allowing for four unique nonintegerrelated frequencies generated from a single reference clock. The reference clock can come from one of two redundant clock inputs, with automatic or manual switchover options. The device is insystem programmable through an I2C interface and has an internal EEPROM for configuration storage and retrieval.
