General Description

The 844244I-04 is a Serial ATA (SATA)/Serial Attached SCSI (SAS)

Clock Generator. For SATA/SAS applications, a 25MHz crystal is

used to produce 150MHz. The 844244I-04 has excellent <1ps phase

jitter performance, over the 12kHz - 20MHz integration range. The

844244I-04-04 is packaged in a small 16-pin TSSOP, making it ideal

for use in systems with limited board space
