IDT, Integrated Device Technology Inc IDT5T9891NLGI

Description
The IDT5T9891 is a 2.5V PLL differential clock driver designed for high-performance computing and data-communications applications. It features programmable skew outputs, allowing for precise timing adjustments. The device has six differential programmable skew outputs in six banks, including a dedicated differential feedback. It can be configured through JTAG or I²C programming, and its internal EEPROM allows for configuration storage and restoration.
