SG-8504CA-PRKF

Overview

The SG-8504CA-PRKF is a programmable XO oscillator from the EPSON SG-8504CA series, manufactured by Epson. It features an LVPECL output interface and operates within a supply voltage range of 2.5V to 3.3V. The device supports frequencies between 50 MHz and 800 MHz with a total frequency stability of ±31.5ppm. It is housed in an 8-SMD, no-lead package (7.00mm x 5.00mm) and functions across a temperature range of -40°C to 85°C. Maximum supply current is 90mA, rising to 70mA in disable mode.

Feature Summary

• Programmable frequency generation capability via distributor ordering notes
• LVPECL output interface for high-speed digital applications
• Integrated enable/disable control functionality
• Surface-mount construction in a compact 8-SMD footprint

Applications

• High-performance computing systems requiring precise clocking
• Telecommunications infrastructure equipment
• Test and measurement instrumentation
• Industrial automation controllers

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement requires verification of availability through authorized distributors or secondary market suppliers. Orders placed through specific distributors may require manual entry of the desired frequency in order remarks. Verify end-of-life status and lead times carefully before integration into new designs due to discontinuation.

Selection Notes

Select this part only if LVPECL outputs and programmable frequencies up to 800 MHz are required. Ensure the design accommodates the 8-SMD package dimensions and thermal requirements for the -40°C to 85°C operating range. Consider that the part is discontinued; verify long-term supply chain viability. Confirm power supply constraints align with the 2.5V to 3.3V specification and current limits.

Part Context

The SG-8504CA-PRKF belongs to the SG-8504CA series of integrated programmable oscillators. This series provides flexible clock solutions for applications demanding precise frequency tuning. The PRKF suffix typically denotes a specific packaging or programming configuration handled by distributors. These components replace fixed-frequency crystals where variable clock speeds are necessary.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, direct replacements must be sourced from manufacturer cross-reference lists or verified by engineering teams. Evaluate pin-compatible alternatives with similar LVPECL outputs and frequency ranges.
