VSC8247YJB-02

Application Specific Clock/Timing Overview

The VSC8247YJB-02 is a quad-channel clock and data recovery (CDR) receiver manufactured by Microchip Technology. It supports serial data rates ranging from 8.5 Gbps to 11.3 Gbps, suitable for high-speed optical interfaces such as SFI and XFI. The device integrates on-chip adaptive electronic dispersion compensation (EDC) to mitigate signal degradation in copper interconnects. It features four independent output channels and operates within a specified voltage range of 1.2V to 3.3V. The component is housed in a 144-ball FCBGA package measuring 13x13 mm, designed for surface-mount applications requiring compact form factors.

Application Specific Clock/Timing Feature Summary

• Quad-channel architecture providing independent clock and data recovery for multiple high-speed serial links simultaneously.
• Integrated adaptive electronic dispersion compensation to enhance signal integrity over lossy transmission media.
• Supports high-speed serial data rates up to 11.3 Gbps for demanding network interface applications.

Application Specific Clock/Timing Applications

• High-speed optical transceiver modules utilizing SFI or XFI interfaces
• Ethernet infrastructure equipment requiring robust clock recovery
• SONET/SDH transport systems with high bandwidth requirements

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix and package type against official Microchip documentation to ensure compatibility with design specifications. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Check for any recent product discontinuation notices or lifecycle changes that may affect long-term supply availability.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring multi-channel CDR functionality with integrated EDC capabilities. Ensure the PCB layout accommodates the 144-ball FCBGA footprint and thermal requirements. Validate input signal parameters against the supported 8.5 Gbps to 11.3 Gbps range before integration.

Application Specific Clock/Timing Part Context

This part belongs to the VSC8247 family of clock and data recovery receivers. It is distinct from development tools like the ADM00824 evaluation board. The model represents a specialized timing solution for high-speed data communication interfaces rather than general-purpose power management or generic timer functions.
