SNLS641 March 2019 DS90UB940N-Q1
PRODUCTION DATA.
The DS90UB940N-Q1 supports the MIPI-defined, ultra-low-power state (ULPS). The DS90UB940N-Q1 D-PHY lanes enter ULPS mode upon software standby mode through 0x6A [2] generated by the processor. When ULPS is issued, all active CSI-2 lanes including the clock and data lanes of the enabled CSI-2 port are put in ULPS according to the MIPI DPHY protocol. D-PHY can reduce power consumption by entering ULPS mode. ULPS is exited by means of a Mark-1 state with a length TWAKEUP followed by a Stop state.
