This brief proposes a 7.5-Gb/s transceiver with adaptive equalization and a bandwidth (BW)-shifting technique for ultrahigh-definition television. By applying dynamic preemphasis calibration and a BW-shifting phase-locked loop/clock and data recovery, the measured jitter of the output data with a 16.88-dB loss cable and clock are enhanced by 49.9% and 40%, respectively. In addition, a data-width-comparison-based adaptive equalizer with a self-adjusting reference voltage is proposed. With a 3.37-MHz sinusoidal jitter, the measured jitter tolerance of the proposed receiver is improved from 1.07UI to 2.97UI. The transmitter and the receiver consume 10.08 and 9.28 mW/Gb/s at 7.5 Gb/s, respectively, and occupy 0.14 and 0.15 mm2, respectively, using a 0.13- μm complementary metal-oxide-semiconductor process.
