Overview
The SG-8503CA-QRKF is a programmable crystal oscillator (XO) from the SG-8503CA series, manufactured by EPSON. It features an LVPECL output format and operates within a frequency range of 50 MHz to 800 MHz. The device supports supply voltages of 2.5V to 3.3V and includes enable/disable functionality. It is housed in a 6-SMD, No Lead surface-mount package and utilizes a crystal base resonator.
Feature Summary
- Dual or quad selectable programmable architecture
- LVPECL output interface for high-speed digital applications
- Integrated enable and disable control pin
- Surface mount design with no lead package
Applications
- High-performance computing systems
- Telecommunications infrastructure equipment
- Network switching and routing devices
- Industrial automation control units
Procurement Notes
Verify the specific ordering suffix QRKF against the official Epson datasheet to confirm the exact frequency, load capacitance, and tolerance specifications. Ensure the required operating temperature range aligns with the component's rated limits. Confirm that the LVPECL output voltage levels match the receiving circuit's input requirements before finalizing procurement.
Selection Notes
Select this component when a programmable frequency solution with LVPECL outputs is required in a compact surface-mount form factor. Consider the SG-8503CA series for applications needing precise frequency generation between 50 MHz and 800 MHz. Evaluate power consumption and thermal performance relative to the system's 2.5V to 3.3V supply constraints.
Part Context
This part belongs to the SG-8503CA series of dual or quad selectable programmable crystal oscillators. It shares the same package footprint and basic electrical characteristics with other variants in the series, differing primarily in programming parameters and output configuration options defined by the specific ordering suffix.
Replacement Considerations
Direct replacements include other SG-8503CA variants with compatible pinouts and LVPECL outputs, such as SG-8503CA-PRLZ, provided the frequency and tolerance specifications match the application requirements. Cross-reference the specific suffix codes to ensure identical electrical performance.
