Electrical Characteristics
4.3.14.2.2
Gated Clock Mode
The SENSB_VSYNC, SENSB_HSYNC, and SENSB_PIX_CLK signals are used in this mode. See
Figure 43. Gated Clock Mode Timing Diagram
A frame starts with a rising edge on SENSB_VSYNC (all the timings correspond to straight polarity of the
corresponding signals). Then SENSB_HSYNC goes to high and hold for the entire line. Pixel clock is valid
as long as SENSB_HSYNC is high. Data is latched at the rising edge of the valid pixel clocks.
SENSB_HSYNC goes to low at the end of line. Pixel clocks then become invalid and the CSI stops
receiving data from the stream. For next line the SENSB_HSYNC timing repeats. For next frame the
SENSB_VSYNC timing repeats.
4.3.14.2.3
Non-Gated Clock Mode
The timing is the same as the gated-clock mode (described in Section 4.3.14.2.2, “Gated Clock Mode”),
except for the SENSB_HSYNC signal, which is not used. See Figure 44. All incoming pixel clocks are
valid and will cause data to be latched into the input FIFO. The SENSB_PIX_CLK signal is inactive (states
low) until valid data is going to be transmitted over the bus.
