Product Details

Fig. 1 Functional Block Diagram

The ASNT6154 is a four-path adjustable continuous-time linear equalizer (CTLE) with two independently controlled analog data equalization channels combined in two groups. Each equalization channel has its own output. The AC response of each path has 8 controls: adjustable DC gain, adjustable linearity, 3 independently adjustable zeros, 2 independently adjustable poles, and additional high-frequency bandwidth control. Input Peak Detectors that represent the input signal amplitude are added to each channel.

The part’s I/Os support CML-type differential interface with on-chip 46Ohm termination to vcc. Matching external terminations are also required. The input terminations can be switched between normal resistance of 46Ohm and high resistance. Further details are available within the product datasheet.
