Abstract
This paper describes a spread spectrum clock generator (SSCG) circuit for DisplayPort 1.2 standard. A Hershey-Kiss modulation profile is generated by dual sigma-delta modulators. The structure generates various modulation slopes to shape a non-linear modulation profile. The proposed SSCG for DisplayPort 1.2 generates clock signals with 5000 ppm down spreading with a Hershey-Kiss modulation profile at three different clock frequencies, 540 MHz, 270 MHz and 162 MHz. The measured peak power reduction is about 15.6 dB at 540 MHz with the chip fabricated using a 0.13 μm CMOS technology.
