TLK1201IRCPR

Drivers, Receivers, Transceivers Overview

The TLK1201IRCPR is a Gigabit Ethernet transceiver manufactured by Texas Instruments, designed for ultrahigh-speed, full-duplex, point-to-point data transmissions. It supports data rates from 600 Mbps to 1.3 Gbps and operates on a single 2.5-V supply voltage with a maximum range of 2.7 V. The device features LVPECL compatible differential I/O and utilizes a monolithic PLL design without requiring external filter capacitors. It is housed in a 64-pin HVQFP PowerPAD package and supports both 10-bit TBI and reduced 5-bit DDR interfaces. The industrial temperature variant (TLK1201I) is characterized for operation between -40°C and +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides comprehensive built-in testability including loopback and PRBS generation/verification
• Features hot plug protection and low power consumption under 200 mW at 1.25 Gbps
• Includes an integrated JTAG interface for manufacturing and system testing

Drivers, Receivers, Transceivers Applications

• Point-to-point baseband data transmission over controlled impedance media
• Interfacing with copper cables or fiber-optic media modules
• CPRI data rate compatible applications at 614 Mbps and 1.22 Gbps

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'R' indicates tape and reel packaging rather than tray. Confirm the 'I' suffix denotes the industrial temperature range (-40°C to 85°C). Ensure the component matches the exact manufacturer part number TLK1201IRCPR to guarantee correct package type and electrical specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring Gigabit Ethernet compliance with low power dissipation. It is suitable for applications needing LVPECL differential signaling and support for both TBI and DDR parallel interfaces. Consider the thermal performance of the PowerPAD package for heat dissipation requirements.

Drivers, Receivers, Transceivers Part Context

This device belongs to the TLK1201 series of Ethernet transceivers. It serves as a functional equivalent to the TNETE2201 but operates on a 2.5-V supply instead of 3.3 V. The series includes variants for commercial and industrial temperature ranges, packaged in 64-pin VQFP formats.

Drivers, Receivers, Transceivers Replacement Considerations

The TLK1201/TLK1201I is functionally equivalent to the TNETE2201. Designers should account for the difference in supply voltage (2.5 V vs 3.3 V) and the removal of required PLL filter capacitors when substituting these devices.
