2 SERUB-16OVT EVM User’s Guide SNLU109 – July 2012
1. DESCRIPTION
The SERUB-16OVT only the Serializer board based on the SERDESUB-16OVT kit. The
SERUB-16OVT is an evaluation kit designed to demonstrate performance and
capabilities of the DS90UB901Q and DS90UB902Q FPD-Link III Serializer/Deserializer
Chipset for use with the OmniVision sensors. This serves as an add-on to the
OmniVision development systems by providing a serialized digital interface between
camera and controller. The chipset enables transmission of a high-speed video data
along with a low latency bi-directional control bus simultaneously over a single twisted
pair cable. The bidirectional control channel of the DS90UB901Q/902Q provides
seamless communication between the camera and Host Controller.
The Serializer board provides LVCMOS inputs and a bidirectional control channel (I
2
C
compatible) from the Image Sensor and is converted to a FPD-Link III LVDS data pair
on the DS90UB901Q Tx board. The DS90UB902Q Rx board receives the FPD-Link III
LVDS serialized data stream and converts it back into parallel LVCMOS signals and
clock together with the bidirectional control channel (I
2
C). The Host Controller
processes the video data from the image sensor and shows it on a display.
This manual is intended for developers who want a convenient way to begin system
development. It is assumed that the reader has a basic understanding of digital video
and still capturing concepts.
