Abstract: Today mobile devices achieve new heights in data rates with every new device. Higher data rates lead to the problem of inter-symbol interference. To overcome this issue, designers can use equalization circuit at the receiver. Equalizer matches the impedance of transmission lines to reduce the inter-symbol interference. Most common equalizer used in digital communication is the adaptive equalizer, which uses training sequences to get the required coefficient settings. The latest MIPI PHY specifications (M-PHY, D-PHY and C-PHY) introduce training sequences for the equalizer settings to reduce inter-symbol interference: adapt sequence in M-PHY, alternate sequence in D-PHY and C-PHY. In addition, C-PHY uses preamble and user-define sequences. This paper describes various training sequences used in MIPI PHYs to reduce inter-symbol interference.
