The LXT317PE is a single-chip transceiver for T1/E1 applications manufactured by Level One Communications. This device is designed to interface with T1 or E1 lines, providing clock recovery, data retiming, and line equalization functions. It's likely used in telecommunications equipment.

Applications

• T1/E1 line cards: Provides the physical layer interface for T1/E1 communication.
• Digital cross-connect systems: Used in digital switching equipment.
• Voice over IP (VoIP) gateways: Provides T1/E1 connectivity for VoIP systems.
• Channel service units/data service units (CSU/DSUs): Interfaces with T1/E1 lines for data transmission.
• Private branch exchanges (PBXs): Used in telephone systems for T1/E1 trunking.

Features

• T1/E1 compatibility: Supports both T1 (1.544 Mbps) and E1 (2.048 Mbps) standards.
• Clock recovery: Extracts timing information from the received signal.
• Data retiming: Aligns the received data with the local clock.
• Line equalization: Compensates for signal attenuation and distortion on the line.
• Jitter attenuation: Reduces jitter in the recovered clock and data.

Benefits

• Reliable T1/E1 communication: Ensures accurate and reliable data transmission over T1/E1 lines.
• Simplified system design: Integrates multiple functions into a single chip.
• Reduced component count: Lowers the cost and complexity of the system.
• Improved performance: Enhances the performance of T1/E1 communication systems.
• Compliance with industry standards: Meets T1/E1 specifications for interoperability.

Additional Details

The LXT317PE likely includes features such as loopback testing and diagnostics for troubleshooting line problems. It typically operates from a single 5V or 3.3V power supply. The package type is likely a surface-mount package (e.g., PQFP) for easy PCB assembly. Refer to the Level One Communications datasheet for detailed specifications, including transmit and receive characteristics, jitter performance, and power consumption. Agere Systems acquired Level One Communications, so documentation may be under either name.
