Aptina Parallel Port Interface
Aptina Parallel Port Interface
This section describes the Aptina Parallel Port interface on the AHA-HSMC.
The AHA-HSMC contains an Aptina Parallel Port interface with a 26-pin header and a 13-pin
header. The 26-pin header is the main connector that connects with Aptina image sensor headboard.
This header includes most of the control and data bus of the Aptina image sensor, and also provides
5V power to the Aptina image sensor headboard. The 13-pin header contains two sets of pixel data
and one shutter control signal. All these signals on Aptina Parallel port are connected to HSMC
connector via two level shift chips for logic-level transformation.
Table 3-2 and Table 3-3 list the
pin assignments of the 26-pin and 13-pin header of Aptina Parallel port, respectively.
