ICS9FG104
General Description
The ICS9FG104 is a Frequency Timing Generator that provides 4 differential output pairs that are compliant to the Intel CK410
specification. It also provides support for PCI-Express and SATA. The part synthesizes several output frequencies from either
a 14.31818 Mhz crystal or a 25 MHz crystal. The device can also be driven by a reference input clock instead of a crystal. It
provides outputs with cycle-to-cycle jitter of less than 50 ps and output-to-output skew of less than 35 ps.
The ICS9FG104 also provides a copy of the reference clock. Frequency selection can be accomplished via strap pins or
SMBus control.

DIF_STOP# - Assertion (transition from '1' to '0')
Asserting DIF_STOP# pin stops all DIF outputs that are set to be stoppable after their next transition. When the SMBus
DIF_STOP tri-state bit corresponding to the DIF output of interest is programmed to a '0', DIF output will stop DIF_True =
HIGH and DIF_Complement = LOW. When the SMBus DIF_STOP tri-state bit corresponding to the DIF output of interest is
programmed to a '1', DIFoutputs will be tri-stated.
DIF_STOP#
DIF
DIF#
DIF_STOP# - De-assertion (transition from '0' to '1')
With the de-assertion of DIF_STOP# all stopped DIF outputs will resume without a glitch. The maximum latency from the
de-assertion to active outputs is 2 - 6 DIF clock periods. If the control register tristate bit corresponding to the output of
interest is programmed to '1', then the stopped DIF outputs will be driven High within 15nS of DIF_Stop# de-assertion to a
voltage greater than 200mV.
