ICS426G

Manufacturer Part Number
ICS426G
Description
Serial ATA/Fibre Channel Clock Synthesizer
Manufacturer
ICST [Integrated Circuit Systems]
Datasheet
MDS 426 B
Description
The ICS426 was developed for serial ATA (SATA) and
fiber channel. It generates a high quality, high
frequency clock output from a low cost frequency
crystal or clock input.
Using Phase-Locked-Loop (PLL) techniques, the
device runs from a standard fundamental mode,
inexpensive crystal or clock input.
