Product Summary
The ICS841S04BGIL is a PLL-based clock generator specifically designed for PCI_Express™Clock Generation applications. This device generates a 100MHz HCSL clock. The device offers a HCSL (Host Clock Signal Level) clock output from a clock input reference of 25MHz. The input reference may be derived from an external source or by the addition of a 25MHz crystal to the on-chip crystal oscillator. An external reference may be applied to the XTAL_IN pin with the XTAL_OUT pin left floating.
