(1) All typical values are at VCC = 1.8 V and TA = 25°C
(2) For EMI reduction purpose, SN65DSI84 supports the center spreading of the LVDS CLK output through the REFCLK or DSI CLK input. The center spread CLK input to the REFCLK or DSI CLK is passed through to the LVDS CLK output A_CLKP/N and/or B_CLKP/N.
