Interface Description
The ACM100 module is intended to support a variety of
automotive applications, so the module has been designed
with flexible mechanical and electrical interfaces. Each of the
interfaces is described in one of the following sections.
Mechanical Interface
The ACM100 module provides a flexible, fastener based
mounting feature. The mounting holes on the ACM100 are
sized for M5 screws. In addition, a variety of planar surfaces
are provided to facilitate the alignment of the camera to the
desired orientation in the vehicle. Figure 2 below defines the
mechanical interfaces and envelope.

Analog Video Interface
The ACM100 module offers an analog video interface. The
camera supports both progressive scan and interlaced modes
as described in the following sections.
Interlaced Video Output Option
It uses a 60 fps imager scan and the pseudo-interlace
scanning option (defined in a later section) to generate 30
frame per second, or 60 field per second video. Figure 3
defines the timing of the video output and the voltage levels for
the 1.4 Vpp waveform.
