CLHS Camera Implementation
The following figure defines the Xtium2 CLHS PX8 camera interface as per the Camera Link HS
(CLHS) specification version 1.0. The key parameters are:
A single camera connector (J3) which is a copper hardwired interface with a thumbscrew
locking mechanism – not an optical interface.
Supports the M-Protocol definition of the Physical and Data Link Layer.
There is one command channel to/from the camera.
Supports single connector cameras which have 1 to 7 data Lanes.

Video Channel uses 1 to 7 Lanes as output by the camera.
The more Lanes used by a camera, the greater is the video bandwidth.
The “Link” is the camera command
channel plus the 1 to 7 Lanes used.

Line Trigger Source Selection for Line scan
Applications
Line scan imaging applications require some form of external event trigger to synchronize line scan
camera exposures to the moving object. This synchronization signal is either an external trigger
source (one exposure per trigger event) or a shaft encoder source composed of a single or dual
phase (also known as a quadrature) signal.
The Xtium2-CLHS PX8 shaft encoder inputs provide additional functionality with pulse drop, pulse
multiply, and pulse direction support.
The following table describes the line-trigger source types supported by the Xtium2-CLHS PX8.
Refer to the Sapera Acquisition Parameters Reference Manual (OC-SAPM-APR00) for descriptions of
the Sapera parameters.
