Abstract :
In this paper, an adaptive 3.125Gbps coaxial cable equalizer is realized in a 0.18-mum CMOS technology. For the length of 15m and 20m Belden 8219 cables, the signal attenuation are -12dB and -16dB, respectively, at 1.5625GHz. Due to the signal attenuation after passing through the coaxial cable, this adaptive 3.125Gbps coaxial cable equalizer compensates the broadband loss to be adaptive to different length of the cables. The core circuit excluding output buffers dissipates only 14.8mW from a 1.8V supply with output swing up to 400mV p-p. The core circuit occupies 0.5times0.63mm2 and the measured timing jitter for a cable of 20m is less than 0.25UI
