ICS844071I Overview
The ICS844071I is a Serial ATA (SATA)/Serial Attached SCSI (SAS) Clock Generator and a HiPerClockS™ member of the HiPerClocks TM family of high performance devices from ICS. The ICS844071I uses an 18pF parallel resonant crystal over the range of 20.833MHz - 28.3MHz. For SATA/SAS applications, a 25MHz crystal is used and either 75MHz or 150MHz may be selected with the FREQ_SEL pin.
