XRT91L33IGTR-F

Overview

The XRT91L33IGTR-F is a multi-rate Clock and Data Recovery (CDR) and clock synchronization IC designed for telecommunications applications. It supports data rates up to 622.08 MHz, making it suitable for SONET/SDH and Ethernet interfaces. The device integrates a phase-locked loop (PLL) for precise frequency synchronization and includes multiplexer capabilities. It operates within a standard industrial temperature range and utilizes a 20-TSSOP surface-mount package.

Feature Summary

• Integrates multi-rate clock and data recovery functionality with embedded phase-locked loop
• Provides clock synchronization and multiplexing for high-speed serial data streams
• Supports LVDS and LVPECL input/output signaling standards

Applications

• SONET/SDH network infrastructure equipment
• Ethernet physical layer interface circuits
• Telecommunications timing and synchronization systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm package integrity and pin alignment prior to assembly. Review the latest manufacturer discontinuation notices for lifecycle status updates. Ensure storage conditions comply with moisture sensitivity level requirements specified in the datasheet to prevent damage during reflow soldering processes.
