The overall timing budget for RJ (Random Jitter) and DJ (Deterministic Jittter) in MIPI C-PHY℠ is roughly defined as TX impairment, 0.15UI. The biggest contribution to the TX impairment is believed to be RJ. However, due to the unique properties of the MIPI C-PHY signal, many jitter influences are not fully studied. This presentation focused on the influence of random jitters to the MIPI C-PHY high speed timing. This investigation offered a reference for MIPI C-PHY designers, and it could help the PHY working group further develop the MIPI C-PHY specification regarding the signal impairment introduced by random jitter.

HeeSoo Lee is the SerDes/DDR product owner in the EEsof EDA group of Keysight Technologies DES division, located in Santa Rosa, Calif. Since 1989, he has held several different positions in Keysight Technologies, Agilent Technologies and Hewlett-Packard, including consulting business manager, technical marketing lead and field applications engineer. Before that, HeeSoo worked for Daeryung Ind. Inc. as an RF/MW circuit design engineer. He has more than 30 years of design and simulation experience in the area of RF, microwave and high-speed digital designs. He graduated with a BSEE degree from the Hankuk Aviation University in South Korea.
Jingshen Liu has been a R&D software engineer with Keysight Technologies since 2018. His work focuses on SERDES and DDR high-speed channel simulations, and he developed the MIPI C-PHY℠ solution in ADS. Before joining Keysight, Jingshen received a Ph.D. in electrical engineering from the University of Houston.
