TLK2501IRCPR

Overview

The TLK2501IRCPR is a single-channel Gigabit Ethernet transceiver manufactured by Texas Instruments. It supports data rates from 1.5 Gbps to 2.5 Gbps, enabling high-speed serial communication over backplane or cable media. The device operates within a supply voltage range of 2.3 V to 2.7 V and functions reliably across an industrial temperature range of -40°C to +85°C. It utilizes a 64-pin HVQFP package with a PowerPad for thermal management. The component integrates a serial interface for control and status monitoring, facilitating integration into complex networking systems requiring robust signal integrity.

Feature Summary

• Supports high-speed serial transmission rates up to 2.5 Gbps for Gigabit Ethernet applications
• Integrates a serial interface for simplified system control and configuration
• Designed for reliable operation in harsh industrial environments with extended temperature coverage

Applications

• High-speed backplane interconnects in telecommunications infrastructure
• Gigabit Ethernet physical layer solutions for network switches and routers
• Industrial automation systems requiring robust serial communication links

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure compatibility with existing board layouts regarding the HVQFP-64 footprint and thermal pad requirements. Cross-reference the part number against current datasheet revisions to confirm pinout consistency.

Selection Notes

Select this component for designs requiring a single-channel transceiver with speeds exceeding 1.5 Gbps. Compare against the TLK2500 if lower speed ranges are sufficient, or the TLK3101 for higher throughput needs. Evaluate power consumption constraints as the device draws significant current during active transmission. Ensure the host processor supports the required serial interface protocol for proper initialization and monitoring.

Part Context

The TLK2501 belongs to Texas Instruments' family of Gigabit Ethernet transceivers, which includes variants like the TLK1501 and TLK2201. These devices share common architectural features such as serial interfaces and similar packaging options. The TLK2501 specifically targets the upper end of the Gigabit Ethernet spectrum, bridging the gap between standard 1 Gbps and 2.5 Gbps applications in networking hardware.

Replacement Considerations

The TLK2501IRCPG4 is a lead-free variant of the same functional device. Verify that any substitute maintains the 1.5 to 2.5 Gbps speed range and HVQFP-64 package dimensions. Ensure electrical characteristics match to avoid signal integrity issues in high-speed designs.
