ESCRIPTION
The ICS844256I is a Cr ystal-to-LVDS Clock
Synthesizer/Fanout Buffer designed for SONET
HiPerClockS™
and Gigabit Ether net applications and is a
member of the HiperClockS™ family of High
Perfor mance Clock Solutions from IDT. The
output frequency can be set using the frequency select
pins and a 25MHz crystal for Ethernet frequencies, or a
19.44MHz crystal for SONET. The low phase noise character-
istics of the ICS844256I make it an ideal clock for these
demanding applications.
F
