Procurement Notes

Verify the specific part number against official EPSON documentation to ensure compatibility with system requirements. Confirm that the LVPECL output type and voltage levels match the target circuit design. Check for any specific ordering suffixes that may affect frequency or package variations. Ensure the supplier provides genuine components from authorized channels to guarantee reliability and performance standards.

Selection Notes

Select this component when a programmable solution with LVPECL outputs is required for frequencies between 50 MHz and 800 MHz. Consider the dual or quad selectable feature if multiple clock domains are needed. Verify the 2.5V to 3.3V supply range aligns with the system power architecture. The 6-SMD package is suitable for space-constrained surface mount designs.

Part Context

The SG-8503CA series belongs to EPSON's line of programmable crystal oscillators. These devices are designed to replace fixed-frequency crystals and resonators, offering greater flexibility in system design. The SG-8503CA variant specifically supports LVPECL outputs, making it suitable for high-speed digital interfaces where signal integrity is critical.

Replacement Considerations

Direct substitutes should be sought from EPSON's SG-8503CA family. Verify that any replacement maintains the same LVPECL output type, frequency range, and package dimensions. Cross-reference with official EPSON cross-reference guides to ensure functional equivalence without compromising timing performance.
