1. DESCRIPTION
The SERDESUB-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 (I2C
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 (I2C). 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.
