ICS841S02BGI REV. C NOVEMBER 1, 2007
PRELIMINARY
GENERAL DESCRIPTION
The ICS841S02I is a PLL-based clock generator
specifically designed for PCI_ExpressClock
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.
The device offers spread spectrum clock output for reduced EMI
applications. An I2C bus interface is used to enable or disable
spread spectrum operation as well as select either a down spread
value of -0.35% or -0.5%.
The ICS841S02I is available in both standard and lead-free
20-Lead TSSOP packages.
