IDT 5V49EE EEPROM Programmable
Integrated Device Technology 5V49EE programmable clock generators are designed for high performance data-communications, telecommunications, consumer, and networking applications. These IDT devices have four internal PLLs, each individually programmable, allowing for four unique non-integer-related frequencies. The frequencies are generated from a single reference clock that can come from one of the two redundant clock inputs. Automatic or manual switchover function allows any one of the redundant clocks to be selected during normal operation. IDT 5V49EE programmable clock generators are in-system, programmable and can be programmed through the use of I²C interface. An internal EEPROM allows the user to save and restore the configuration of the device without having to reprogram it on power-up.
