Overview
The SG-8503CA-QRLZ is a dual or quad selectable programmable crystal oscillator manufactured by Epson. It supports a frequency range of 50 MHz to 800 MHz and operates on a supply voltage of 2.5V to 3.3V. The device features LVPECL output signals and includes enable/disable functionality. It is housed in a 6-SMD, no lead package and functions as a standard XO (Xtal Oscillator).
Feature Summary
- Dual or Quad Selectable Output Configuration
- Programmable Frequency Range from 50 MHz to 800 MHz
- LVPECL Output Signal Type
- Integrated Enable/Disable Control
Applications
- High-speed digital signal processing systems
- Telecommunications equipment requiring precise clocking
- Network infrastructure components
- Industrial control systems with multiple clock domains
Procurement Notes
Verify the specific ordering suffix matches the required output configuration and frequency. Confirm that the LVPECL output type aligns with the target circuit design requirements. Ensure the operating temperature range meets the environmental specifications of the intended application environment before finalizing procurement.
Selection Notes
Select this component when a flexible clock source with selectable dual or quad outputs is required. Consider the LVPECL output drive capability for impedance matching needs. Evaluate the programmability options against fixed-frequency alternatives to determine if dynamic adjustment benefits the system architecture.
Part Context
This part belongs to the SG-8503CA series of programmable oscillators. It shares the core technology with other variants in the family but differs in packaging and specific electrical characteristics. The SG-8503CA-QRLZ represents a surface-mount solution designed for compact electronic assemblies.
Replacement Considerations
Direct substitutes include other SG-8503CA variants such as SG-8503CA-PRLZ, provided the output configuration and pinout compatibility are verified. Cross-reference datasheets to ensure equivalent electrical performance and mechanical dimensions.
