The TLK3101 is a member of the transceiver family of multigigabit transceivers, intended for use in ultrahigh-speed bidirectional point-to-point data transmission systems. The TLK3101 supports an effective serial interface speed of 2.5 Gbps to 3.125 Gbps providing up to 2.5 Gbps of data bandwidth. The TLK3101 is functionally identical to the TLK1501, a 0.6 Gbps to 1.5 Gbps transceiver, and the TLK2501, a 1.6 Gbps to 2.5 Gbps transceiver, providing a wide range of performance solutions with no significant board layout changes. NOTE: The TLK3101 does have an integrated termination resistance unlike the TLK2501 and TLK1501.

The primary application of this chip is to provide very high-speed I/O data channels for point-to-point baseband data transmission over controlled impedance media of approximately 50 .
