Pixel Output Interfaces

Parallel Interface

The parallel pixel data interface uses these output-only signals:

•FRAME_VALID

•LINE_VALID

•PIXCLK

•DOUT[11:0]

The parallel pixel data interface is disabled by default at power up and after reset. It can

be enabled by programming R0x301A. Table 5 shows the recommended settings.

When the parallel pixel data interface is in use, the serial data output signals can be left

unconnected. Set reset_register [bit 12 (R0x301A[12] = 1)] to disable the serializer while

in parallel output mode.

Output Enable Control

When the parallel pixel data interface is enabled, its signals can be switched asynchro-

nously between the driven and High-Z under pin or register control, as shown in Table 4.

Configuration of the Pixel Data Interface

Fields in R0x301A are used to configure the operation of the pixel data interface. The

supported combinations are shown in Table 5.

Power up default.

Serial pixel data interface and its clocks are enabled. Transitions to soft standby are

synchronized to the end of frames on the serial pixel data interface.

Parallel pixel data interface, sensor core data output. Serial pixel data interface and its

clocks disabled to save power. Transitions to soft standby are synchronized to the end of

frames in the parallel pixel data interface.
