Description
Electronic Component Model: 5V926PGI is a programmable clock generator designed for high-performance applications in data communications, telecommunications, consumer, and networking. It features three internal PLLs, each individually programmable, allowing for three unique non-integer-related frequencies. The frequencies are generated from a single reference clock, which can be sourced from two redundant clock inputs. It also has a glitchless automatic or manual switchover function for selecting the redundant clocks during normal operation. The IDT5V9885T can be programmed through the use of the I2C or JTAG interfaces, even during normal operation. It has an internal EEPROM for saving and restoring the device configuration without requiring reprogramming on power-up. Additionally, it supports JTAG boundary scan.
