The XRT94L31IB-F is a Quad T1/E1/J1 Long Haul Transceiver manufactured by Exar Corporation. It's designed to provide a robust interface between network equipment and T1/E1/J1 lines, integrating four independent transceivers into a single package. This reduces board space and component count, making it ideal for applications requiring multiple T1/E1/J1 connections, such as line cards and access nodes.

Applications:

• T1/E1/J1 Line Cards
• Digital Cross-Connect Systems (DCS)
• Private Branch Exchange (PBX) Systems
• Voice over IP (VoIP) Gateways
• Channel Service Units/Data Service Units (CSU/DSU)
• Wireless Base Stations
• Network Interface Equipment

Features:

• Quad (4-Channel) T1/E1/J1 Transceiver
• Long Haul Line Interface
• Integrated Pulse Shaping and Line Build-Out
• Jitter Attenuation
• Clock Recovery
• Individual Channel Loopback Testing
• Comprehensive Diagnostic Features
• Low Power Consumption

Benefits:

• Reduced Board Space: Integrating four transceivers into one package saves valuable board space.
• Cost Savings: Lower component count reduces overall system cost.
• Improved Signal Integrity: The long-haul line interface ensures reliable data transmission over extended distances.
• Simplified Design: The integrated pulse shaping, line build-out, and clock recovery simplify the design process.
• Enhanced Performance: Jitter attenuation and clock recovery contribute to improved signal quality.
• Easy Diagnostics: Individual channel loopback testing allows for easy system diagnostics.
• Lower Power: The low power consumption design is suitable for high-density applications.

Additional Details:

The XRT94L31IB-F supports T1 (1.544 Mbps), E1 (2.048 Mbps), and J1 data rates. It contains pulse shaping and line build-out capabilities for optimal signal transmission over varied cable types and lengths. Jitter attenuation reduces the accumulation of jitter, and the clock recovery function ensures accurate data sampling. Individual channel loopback testing streamlines system diagnostics. Typically operates on a 3.3V power supply. Comprehensive diagnostic features monitor system performance. The package is optimized for thermal performance.
