The SN75LVPE5421 receivers feature a continuous-time linear equalizer (CTLE) that applies high-frequency boost and low-frequency attenuation to help equalize the frequency-dependent insertion loss effects of a passive channel. The receivers implement two stage linear equalizer for wide range of equalization capability. The equalizer stages also provide flexibility to make subtle modifications of mid-frequency boost for best EQ gain profile match with wide range of channel media characteristics. The EQ profile control feature is only available in SMBus/I2C Mode. In Pin Mode the settings are optimized for FR4 traces.
Table 6-2 shows available equalization boost through EQ control pins or SMBus/I2C registers. In Pin Control mode EQ1 and EQ0 pins set equalization boost for all channels. In I2C Mode individual channels can be independently programmed for EQ boost.
