SG-8504CA-QRLZ

Overview

The EPSON SG-8504CA-QRLZ is a programmable crystal oscillator (XO) from the SG-8504CA series, manufactured by Epson. It features an LVPECL output format and operates within a supply voltage range of 2.5V to 3.3V. The device supports a frequency range of 50 MHz to 800 MHz with a total frequency stability of ±50ppm. It includes enable/disable functionality, drawing a maximum supply current of 90mA during operation and 40mA when disabled. The component is housed in an 8-SMD, no-lead package measuring 7.00mm x 5.00mm x 1.70mm. It is designed for surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Procurement Notes

This component is currently listed as obsolete or discontinued by the manufacturer. Procurement should focus on verifying availability through authorized distributors or surplus suppliers. Ensure that any replacement strategy accounts for the end-of-life status. Verify RoHS compliance and specific packaging details if sourcing from secondary markets. Confirm that the programming service requirements are met before finalizing acquisition plans.

Selection Notes

Select this part only if LVPECL output compatibility and the specific 8-SMD footprint are required. The programmable nature necessitates coordination with the supplier for frequency configuration. Consider the ±50ppm stability specification against system jitter requirements. Evaluate the 90mA current draw against available power budgets. Verify that the 2.5V to 3.3V supply range matches the target board design constraints.

Part Context

The SG-8504CA-QRLZ belongs to Epson's SG-8504CA series of integrated programmable oscillators. This series is designed for applications requiring flexible frequency options in a compact surface-mount package. The QRLZ suffix typically denotes a specific tape and reel packaging configuration for automated assembly. The series emphasizes low phase noise and high reliability for timing-critical electronic designs.

Replacement Considerations

As the SG-8504CA-QRLZ is discontinued, direct substitutes must be sourced from Epson's current portfolio or competitors offering equivalent LVPECL programmable oscillators. Verify pin compatibility and electrical specifications such as supply voltage and current consumption. Ensure the replacement maintains the required frequency stability and operating temperature range.
