IDT, Integrated Device Technology Inc 841S104EGILF

Description
The ICS841S1041 is a PLL-based clock synthesizer designed for PCI Express Clock applications. It generates a 100MHz differential HCSL clock from an input reference of 25MHz. The input reference can be derived from an external source or by adding a 25MHz crystal to the on-chip crystal oscillator. The device offers spread spectrum clock output for reduced EMI applications. An I2C bus interface enables or disables spread spectrum operation and selects a down spread value of -0.35% or -0.5%. The ICS841S1041 is available in a lead-free 24-Lead package.
