Document Table of Contents Continuous Time Linear Equalization (CTLE)

The CTLE boosts the signal that is attenuated due to channel characteristics. Each receiver buffer has independently programmable equalization circuits. These equalization circuits amplify the high-frequency component of the incoming signal by compensating for the low-pass characteristics of the physical medium. The CTLE can support both DC and AC gain.

DC gain circuitry provides an equal amplification to the incoming signal across the frequency spectrum. AC gain circuitry provides amplification to the high-frequency spectrum gain of the incoming signal. Refer to Figure 172.

Cyclone® 10 GX transceivers support high gain mode CTLE.
