SG-8504CA-QRLF

Overview

The SG-8504CA-QRLF is a programmable crystal oscillator (XO) manufactured by EPSON, designed for high-frequency applications. It operates within a frequency range of 50 MHz to 800 MHz with a total frequency stability of ±50ppm. The device supports LVPECL output mode and functions on a supply voltage of 2.5V to 3.3V. It features an enable/disable function and draws a maximum supply current of 90mA. The component is housed in an 8-SMD, no-lead package measuring 7.00mm x 5.00mm with a maximum seated height of 1.70mm. It is rated for operation between -40°C and +85°C.

Feature Summary

• Programmable frequency generation capability within the 50 MHz to 800 MHz range
• LVPECL output interface for high-speed digital signaling
• Integrated enable and disable control functionality
• Compact surface-mount packaging suitable for space-constrained designs

Applications

• High-speed data communication systems requiring precise clocking
• Network infrastructure equipment such as routers and switches
• Test and measurement instruments needing stable frequency references
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify that the specific frequency requirement matches the programming capabilities supported by the supplier or distributor. Confirm the LVPECL output compatibility with the target circuit design. Ensure the 8-SMD package dimensions fit the PCB footprint constraints. Check for any end-of-life status updates from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a programmable solution is required for frequencies up to 800 MHz. Consider the LVPECL output drive strength and power consumption characteristics against system requirements. Evaluate the ±50ppm stability specification against the jitter tolerance of the receiving devices. Ensure the operating temperature range aligns with the environmental conditions of the intended application.

Part Context

This part belongs to the SG-8504CA series of integrated programmable oscillators from EPSON. The series is characterized by its flexibility in frequency selection and compact form factor. These components are engineered to replace fixed-frequency crystals in designs requiring post-manufacturing frequency adjustments or customization.

Replacement Considerations

Check for direct substitutes within the SG-8504CA family that may offer updated availability. Verify pinout and electrical parameter compatibility if considering alternative manufacturers. Review datasheet revisions for any changes in mechanical dimensions or electrical specifications.
