The ASNT6153 is a two-channel adaptive continuous-time linear equalizer (CTLE) with two independently controlled analog data equalization paths per channel. Each equalization path has its own output. AC response of each path has 6 controls: adjustable DC gain, 3 independently adjustable zeros, and 2 independently adjustable poles. 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. All operational modes of the chip are controlled by a Control Block that communicates with an external computer through a high-speed 3-wire serial interface.
The part operates with a positive supply vcc = +3.3V for the main data paths, and an additional positive supply v5p0 = +5.0V for the AC control circuitry. The negative supply rail vee should be connected to external ground. The part can also operate with a negative supply vee = -3.3V for the main data paths, and an additional positive supply v5p0 = +1.7V for the AC control circuitry. In this case the positive supply rail vcc should be connected to external ground.
