Functional Description
11.0 DIGITAL VIDEO PORT
The captured image is placed onto a flexible 12-bit digital port as
shown in Figure 10. The digital video port consists of a program-
mable 12-bit digital Data Out Bus (d[11:0]) and three program-
mable synchronisation signals (hsync, vsync, pclk).
By default the synchronisation signals are configured to operate
in “master” mode. They can be programed to operate in “slave”
mode.
The following sections are a detailed description of the timing
and programming modes of digital video port.
Pixel data is output on a 12-bit digital video bus. This bus can be
tri-stated by asserting the TriState bit in the VIDEOMODE1 reg-
ister.
11.1
A programmable matrix switch is provided to map the output of
the internal pixel framer to the pins of the digital video bus as
illustrated in Figure 35.

This feature allows a programmable digital gain to be imple-
mented when connecting the sensor to 8 or 10 bit digital video
processing systems as illustrated in Figure 36. The unused bits
on the digital video bus can be optionally tri-stated.

Synchronisation Signals in Master Mode
By default the sensor’s digital video port’s synchronisation sig-
nals are configured to operate in master mode. In master mode
the integrated timing and control block controls the flow of data
onto the 12-bit digital port, three synchronisation outputs are
provided:
11.2
The pixel clock output pin, pclk, is provided to act as a synchro-
nisation reference for the pixel data appearing at the digital
video out bus pins d[11:0]. This pin can be programmed to oper-
ate in two modes:
• In free running mode the pixel clock output pin, pclk, is always
• In data ready mode, the pixel clock output pin (pclk) will pro-

running with a fixed period. Pixel data appearing on the digital
video bus d[11:0] are synchronized to a specified active edge
of the clock as shown in Figure 37.
duce a pulse with a specified level every time valid pixel data
appears on the digital video bus d[11:0] as shown in Figure
38.
