25 / 26 page Si570/Si571 Rev. 0.3 25 DOCUMENT CHANGE LIST Revision 0.1 to Revision 0.2 Updated " Description" on page 1. Updated "1. Detailed Block Diagrams" on page 4 for both XO and VCXO. Updated the Nominal Control Voltage in Table 2, “VC Control Voltage Input,” on page 5. Updated tables to reflect slight performance differences between Si570 and Si571. Added detail to the "3.2. Frequency Programming Details" on page 12. Revised "3.2.3. Programming Procedure" on page 12. Procedure now requires use of two frequency configuration register sets. Procedure now recommends disabling output at powerup to protect equipment not expecting the default output frequency. Added second frequency configuration register set to the register tables. Added frequency configuration select register. Updated "7. Ordering Information" on page 21 to be consistent with the Si55x series devices. Revision 0.2 to Revision 0.3 Updated Table 1, “Recommended Operating Conditions,” on page 5. Device maintains stable operation over –40 to +85 ºC operating temperature range. Supply current specifications updated. Updated Table 4, “CLK± Output Levels and Symmetry,” on page 7. Updated LVDS differential peak-peak swing specifications. Updated Table 5, “CLK± Output Phase Jitter (Si570),” on page 7. Updated Table 6, “CLK± Output Phase Jitter (Si571),” on page 8. Updated Table 7, “CLK± Output Period Jitter,” on page 9. Revised period jitter specifications. Updated Table 10, “Absolute Maximum Ratings,” on page 10 to reflect the soldering temperature time at 260 ºC is 20–40 sec per JEDEC J-STD-020C. Updated device programming procedure in Section "3.2.3. Programming Procedure" on page 12. Updated "7. Ordering Information" on page 21. Changed ordering instructions to revision D. Added "8. Si57x Mark Specification" on page 22. |
