8.2.1.3 Application Curves

The DS160PR410 is a linear redriver that can be used to extend channel reach of a PCIe link. Normally, PCIe-compliant TX and RX are equipt with signal-conditioning functions and can handle channel losses of up to 28 dB at 8 GHz. With the DS160PR410, the total channel loss between a PCIe root complex and an end point can be up to 45 dB at 8 GHz.

Figure 5 shows an electric link that models a single channel of a PCIe link and eye diagrams measured at different locations along the link. The source that models a PCIe TX sends a 16-Gbps PRBS-15 signal with P7 presets. After a transmission channel with –30 dB at 8-GHz insertion loss, the eye diagram is fully closed. The DS160PR410 with its CTLE set to the maximum (18-dB boost) together with the source TX equalization compensates for the losses of the pre-channel (TL1) and opens the eye at the output of the DS160PR410.

The post-channel (TL2) losses mandate the use of PCIe RX equalization functions such as CTLE and DFE that are normally available in PCIe-compliant receivers.
