Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required frequency and tolerance specifications. Confirm that the LVPECL output format aligns with the target circuit design requirements. Check package dimensions against PCB footprint constraints. Ensure supply voltage levels match the 2.5 V to 3.3 V operational range. Validate environmental ratings if operating outside standard conditions.
Selection Notes
Select this component when a programmable solution with LVPECL outputs is required. Consider the 50 MHz to 800 MHz frequency range for system clock needs. Evaluate the 90 mA current consumption against power budget constraints. Assess the 8-SMD package size for board space limitations. Verify compatibility with existing programming tools like SG-Writer II for configuration.
Part Context
This model belongs to the SG-8504CA series of programmable SPXOs from EPSON. The series is characterized by its flexibility in frequency selection and robust performance in demanding environments.
