LVDS data outputs

The CMV2000 has LVDS (low voltage differential signaling) outputs to transport the image

data to the surrounding system. Next to 16 data channels, the sensor also has two other LVDS

channels for control and synchronization of the image data. In total, the sensor has 18 LVDS

output pairs (2 pins for each LVDS channel):

•

16 Data channels

•

1 Control channel

•

1 Clock channel

This means that a total of 36 pins of the CMV2000 are used for the LVDS outputs (32 for data

+ 2 for LVDS clock + 2 for control channel). See the pin list for the exact pin numbers of the

LVDS outputs.

The 16 data channels are used to transfer the 10-bit or 12-bit pixel data from the sensor to the

receiver in the surrounding system.

The output clock channel transports a clock, synchronous to the data on the other LVDS

channels. This clock can be used at the receiving end to sample the data. This clock is a DDR

clock which means that the frequency will be half of the output data rate. When 480 Mbps

output data rate is used, the LVDS output clock will be 240 MHz.

The data on the control channel contains status information on the validity of the data on the

data channels. Information on the control channel is grouped in 10-bit or 12-bit words that are

transferred synchronous to the 16 data channels.
