TLK2208BZPV

Drivers, Receivers, Transceivers Overview

The TLK2208BZPV is an eight-channel Gigabit Ethernet transceiver from Texas Instruments, designed for full-duplex point-to-point data transmission compliant with IEEE 802.3z. It supports data rates ranging from 1.0 Gbps to 1.3 Gbps per channel, providing up to 8.32 Gbps of aggregate bandwidth. The device operates on a single 1.8-V supply and consumes less than 1.3 W at 1.25 Gbps. It features differential VML transmit outputs and PECL-compatible receive inputs, housed in a compact 19x19-mm, 289-terminal BGA package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Confirm that the component meets the required commercial temperature range specifications for the intended deployment environment before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high port density and low power consumption for Gigabit Ethernet applications. Ensure the host protocol device supports the selected DDR timing interface mode and that the PCB layout accommodates the 289-terminal BGA footprint with appropriate thermal management strategies.

Drivers, Receivers, Transceivers Part Context

This device belongs to the third generation of Gigabit Ethernet transceivers from Texas Instruments. It combines high port density with ultralow power consumption in a small form-factor footprint. The design utilizes advanced low-power 0.18-µm CMOS technology to achieve its performance metrics while maintaining compliance with industry standards.

Drivers, Receivers, Transceivers Replacement Considerations

The ball out and footprint are compatible with the PMC-Sierra PM8352 8-channel transceiver in multiplex channel mode. Verify functional equivalence and register mapping before substituting this component with alternative devices in existing designs.
