XG-2121CA 156.2500M-PGRN0

Oscillators Overview

The XG-2121CA 156.2500M-PGRN0 is a Surface Acoustic Wave (SAW) oscillator manufactured by Epson Timing. It operates at a nominal frequency of 156.25 MHz with an LVPECL output format. The device requires a supply voltage of 2.5V and features an Enable/Disable function for power management. It is housed in a 6-SMD, No Lead package measuring 7.00mm x 5.00mm x 1.2mm. The component supports operation within a temperature range of 0°C to +70°C.

Oscillators Feature Summary

• Integrates SAW resonator technology for stable frequency generation
• Provides LVPECL output interface for high-speed digital synchronization
• Includes hardware enable/disable control capability

Oscillators Applications

• High-speed data communication systems requiring precise clocking
• Network infrastructure equipment utilizing 156.25 MHz reference signals
• Test and measurement instruments needing low-jitter timing sources

Oscillators Procurement Notes

Verify the specific suffix PGRN0 against official Epson documentation to confirm the exact tape-and-reel packaging configuration and enable/disable functionality. Ensure that the 2.5V supply requirement aligns with the target system design, as this variant differs from other voltage options in the series. Cross-reference the part number with current manufacturer lifecycle status to avoid obsolescence risks during procurement.

Oscillators Selection Notes

Select this model when a 156.25 MHz frequency is required with LVPECL outputs in a compact SMD footprint. Consider the 2.5V operating voltage constraint compared to 3.3V alternatives like the XG-2102CA series. Evaluate the need for the enable/disable feature if power management is critical. Confirm that the SAW technology meets the phase noise and stability requirements for the specific application environment.

Oscillators Part Context

This component belongs to the XG-2121CA series of SAW oscillators from Epson Timing. The series offers various frequency options and output formats tailored for telecommunications and networking applications. The XG-2121CA specifically targets markets requiring reliable clock sources with moderate size constraints and standardized pin configurations for surface-mount assembly.

Oscillators Replacement Considerations

Publicly confirmed substitutes include the XG-2121CA 156.2500M-PGRN0 variants with different packaging suffixes such as PGRN0 or PHPAL0, provided they maintain identical electrical specifications. Direct replacement with the XG-2102CA series is possible only if the system supports 3.3V operation instead of 2.5V.
