The 844071 is a Serial ATA (SATA)/Serial Attached SCSI (SAS) Clock Generator and a member of the family of high performance devices from IDT. The 844071 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. The 844071 has excellent <1ps phase jitter performance, over the 900kHz - 7.5MHz integration range. The 844071 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.

Features
