Overview
The SG-8503CA 125.0M 156.2M-APRLZ3 is a pin-configurable LVPECL crystal oscillator manufactured by EPSON. It operates within a voltage range of 2.5V to 3.3V and features a 6-SMD, No Lead package. The device supports dual output configurations with selectable frequencies of 125.0 MHz and 156.2 MHz. Frequency stability is rated at ±50ppm, and it functions reliably across an operating temperature range of -40°C to 85°C.
Feature Summary
- Pin-configurable architecture allows selection between different output modes
- Supports dual output signals via LVPECL interface
- Selectable frequency options for flexible system integration
Applications
- High-frequency data transmission systems
- Telecommunications equipment clocking
- Network infrastructure synchronization
Procurement Notes
Verify the specific ordering suffix APRLZ3 to ensure correct packaging and frequency configuration. Confirm that the required output mode matches the pin configuration settings defined in the official datasheet. Ensure supply chain partners provide RoHS compliance documentation as indicated in public listings.
Selection Notes
Select this component when dual LVPECL outputs are required from a single package. Consider the ±50ppm stability requirement against system jitter specifications. Evaluate the 6-SMD footprint constraints against PCB layout guidelines. Verify power supply compatibility with the 2.5V to 3.3V operating range.
Part Context
This part belongs to the SG-8503CA series of programmable crystal oscillators. It shares the same package and basic electrical characteristics with other variants in the family, differing primarily in frequency selection and pin configuration options. The series is designed for applications requiring precise timing signals.
Replacement Considerations
Direct substitutes include other SG-8503CA variants with matching pin configurations. Cross-reference the specific frequency tolerance and package dimensions before substitution. Verify that alternative components support the same LVPECL output levels and operating temperature range.
