ICS426
Serial ATA/Fibre Channel Clock Synthesizer
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.
Features
• Packaged in 16 pin TSSOP
• Input crystal or clock frequency of 25 MHz (typical)
• Supports serial ATA Generation 1
• Supports Fiber Channel
• Duty cycle of 45/55
• Operating voltage of 3.3V
• Advanced, low power, CMOS process
