1047P-BT

Overview

The Agere Systems 1047P-BT is a dual differential transceiver circuit designed for transmitting and receiving digital data over balanced transmission lines. It integrates two line drivers and two line receivers within a single package, providing compatibility with Lucent Technologies Microelectronics Group differential drivers and receivers. The device features logic conversion between TTL input levels and differential pseudo-emitter coupled logic (ECL) output levels, ensuring robust signal integrity. It operates on a single 5.0 V ± 5% supply and supports a maximum data rate of 400 Mbits/s. The component meets Enhanced Small Device Interface (ESDI) standards and includes common enable controls for each driver/receiver pair.

Feature Summary

• Dual differential transceiver architecture with integrated drivers and receivers
• Logic conversion from TTL inputs to differential ECL outputs
• High output driver capability suitable for 50 Ω loads
• Common enable control for each driver/receiver pair

Applications

• Balanced transmission line data communication
• Enhanced Small Device Interface (ESDI) systems
• Digital data transmission over differential pairs

Procurement Notes

Verify the manufacturer designation as Agere Systems or its successor entities, noting that Agere was spun off from Lucent Technologies. Confirm the specific package type and pinout configuration against official datasheets before integration. Ensure the component meets the required operating temperature range of –40 °C to +125 °C for your application environment. Check for availability of original versus reconditioned units if sourcing from third-party distributors.

Selection Notes

Select this component when a dual differential transceiver is required for ESDI-compatible applications. It is suitable for designs needing TTL-to-ECL level conversion with high-speed performance up to 400 Mbits/s. Consider the 5.0 V supply requirement and the specific propagation delays: 2.0 ns for drivers and 4.0 ns for receivers. Evaluate the need for common enable functionality per pair to manage bus states effectively in your system design.

Part Context

This part belongs to the family of differential transceivers produced by Agere Systems, formerly part of Lucent Technologies. These devices were commonly used in high-speed digital interfaces requiring reliable data transmission over balanced lines. The 1047P-BT specifically addresses the need for integrated transmit and receive capabilities in a compact form factor, supporting legacy and specialized industrial interface standards.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative dual differential transceivers, particularly regarding voltage levels, data rates, and package dimensions.
