2.7 Data Bus
The Piranha provides 8 bits of data in EIA-644 (LVDS) differential format at 25MHz. The
data bus also includes synchronization signals STROBE and LVAL.
Pixel Order
The example below illustrates the order in which the CT-P1 outputs pixels. (For CL-P1,
disregard OS3 and OS4) The example uses a 1024-pixel array, but the pattern is the same
for 2048 and 4096-pixel arrays.

STROBE
STROBE is a pixel clock signal for digital data. It is continuous, toggling even when data
is not valid. Data is valid on its
rising edge
when LVAL is high.
LVAL (Horizontal Synchronization)
LVAL high indicates the camera is outputting a valid line of pixels.
IMPORTANT:
This camera’s data is
valid on the
rising
edge
of STROBE, unlike
previous DALSA
cameras, which used the
falling edge.
