Overview

All outputs are always used to send data, but if you use less than 16 channels, some channels

will have duplicate data. For example, if you multiplex to 4 channels, outputs 6, 7 and 8 will

have identical data as output 5.

Table 8 shows an overview of which channel data is on which output at a certain output mode.

Control channel

The CMV2000 has one LVDS output channel dedicated for the valid data synchronization and

timing of the output channels. The end user must use this channel to know when valid image

data or training data is available on the data output channels.

The control channel transfers status information in 10-bit or 12-bit word format. Every bit of the

word has a specific function. Next table describes the function of the individual bits, but only

the DVAL, LVAL and FVAL signal are necessary to know when to sample the image data.
