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
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.
