The ASNT6152-KMM is an adaptive continuous-time linear equalizer (CTLE) with two independently controlled analog data channels, each channel with two identical and independently controlled equalization stages. The DC-gain in the equalization stages is automatically adjusted to 0dB. The DC-gain of the Output Buffer (OB) can be externally adjusted.

The first channel of the ADE features a built-in Error Detector (ED) that generates an output signal proportional to the absolute value of the difference between a recovered signal and an ideal signal. The ED can be turned off to save power.

The part’s I/Os support CML-type differential interface with on-chip 50Ohm termination to vcc. External 50Ohm termination is also required. AC-coupling for both analog data channels is required.

All operational modes of the chip are controlled through a high-speed 3-wire serial interface. The part operates with a positive supply vcc = +3.3V for the analog section, and a digital supply vdd = +1.3V for theSPI interface. The negative supply rail vee should be connected to external ground.
