The TLK10081 is a multi-rate link aggregator intended for use in high-speed bi-directional point-to-point data transmission systems. The device allows for a reduction in the number of physical links required for a certain data throughput by multiplexing multiple lower-rate serial links into higher-rate serial links.

The TLK10081 has a low-speed interface which can accommodate one to eight bidirectional serial links running at rates from 250 Mbps to 1.25 Gbps (maximum of 10 Gbps total throughput). The device’s high speed interfaces can operate at rates from 1 Gbps to 10 Gbps. The high speed interface is designed to run at 8 x the low speed serial rate regardless of the number of lanes connected. Filler data will be placed on any unused lanes in order to keep the interleaved lane ordering constant. This allows for low speed lanes to be hot swapped during normal operation without requiring a change in configuration.

A 1:1 mode is also supported for data rates ranging from 0.5 Gbps to 2.5 Gbps, whereby both low speed and high speed are rate matched. The TX and RX datapaths are also independent, so TX may operate in 8:1 mode while RX operates in 1:1 mode. This independence is restricted to using the same low speed line rate. For example, the TX can operate at 8 × 1.25 Gbps while RX operates at 1 × 1.25 Gbps.Read more
