Procurement Notes

Verify the specific ordering suffix against official Epson documentation to confirm the exact output configuration and packaging details. Ensure compatibility with system voltage requirements of 2.5 V to 3.3 V. Confirm that the LVPECL output type matches the receiving component's input specifications. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a fixed 156.2 MHz frequency is required with LVPECL outputs. Consider the 50 PPM stability requirement for the application environment. Evaluate the 7 mm x 5 mm footprint against available PCB space. Compare power consumption limits against system thermal constraints. Verify pin configuration options if multiple outputs are needed.

Part Context

This model belongs to the SG-8503CA series of pin-configurable oscillators from Epson Timing. The series offers flexibility in output configuration through pin selection. The SG-8503CA variant specifically targets applications requiring dual or quad selectable outputs. It complements other models like SG-8504CA in providing versatile timing solutions for complex electronic systems.

Replacement Considerations

Direct substitutes may include other SG-8503CA variants with different frequency or voltage ratings. Check Epson datasheets for equivalent parts with matching LVPECL outputs and 156.2 MHz frequency. Verify package dimensions and pinout compatibility before substitution. Consult official replacement guides for cross-referencing similar timing devices.
