Product Summary

The TLK3143 is a multigigabit transceiver, intended for use in ultrahigh-speed bidirectional point-to-point data transmission systems. The TLK3143 supports an effective serial interface speed of 2.5 Gbps to 3.125 Gbps providing up to 2.5 Gbps of data bandwidth. The TLK3143 is functionally identical to the TLK1501, a 0.6 Gbps to 1.5 Gbps transceiver, and the TLK2501, a 1.6 Gbps to 2.5Gbps transceiver, providing a wide range of performance solutions with no significant board layout changes.
