Multi-Camera Sync
The MT9M114 supports more than one device to be connected in a “daisy-chain” type
configuration. One of the devices will act as the master and the remainder will be slaves.
A typical connection diagram is shown inFigure 27. All of the MT9M114 that are to
communicate are:
• Connected in a daisy-chain using SADDR as an input and CHAIN as an output.
• Clocked from a common clock source
• Controlled from a single master, presumed to be under software control of a host
system.

SADDR is normally used as a static input that selects between two slave device addresses
(See Figure 28. In order to implement the multi-sync function this input now has addi-
tional functionality that does not interfere with its use as device address selection.
