Overview
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 is packaged in a small 16-pin TSSOP, making it ideal for use in systems with limited board space.
Features
- Four differential LVDS output pairs
- Crystal oscillator interface, 18pF parallel resonant crystal (20.833MHz – 28.3MHz)
- Output frequency range: 125MHz – 170MHz
- VCO range: 500MHz – 680MHz
- RMS phase jitter at 150MHz, using a 25MHz crystal (12kHz – 20MHz): 0.9ps (typical) @ 3.3V
- Full 3.3V or 2.5V output supply modes
- -40°C to 85°C ambient operating temperature
- Available in lead-free (RoHS 6) package
