8.1 Overview
The DS90UB964-Q1 is a camera hub that accepts four camera inputs from a FPD-Link III interface. The device
combines data streams from multiple camera sources onto one or two MIPI CSI-2 port(s) with up to 4 data lanes
each port.
8.2 Functional Block Diagram
The DS90UB964-Q1 is a camera hub that aggregates up to four inputs acquired from a FPD-Link III stream and
transmitted over a MIPI camera serial interface (CSI-2). When coupled with DS90UB913AQ/913Q/933Q FPD-
Link III serializers, the DS90UB964-Q1 receives data streams from multiple imagers to be multiplexed on the
same CSI-2 links.
The DS90UB964-Q1 provides two MIPI CSI-2 ports, configuration with 4 lanes per port up to 1.6 Gbps per lane.
The second MIPI CSI-2 output port is available to provide additional bandwidth, or offers a second replicated
output. The DS90UB964-Q1 can support multiple data formats (programmable as RAW, YUV, RGB) and
different camera resolutions. The CSI-2 Tx module accommodates both image data and non-image data
(including synchronization or embedded data packets).
The DS90UB964-Q1 CSI-2 interface combines each of the camera data streams into packets designated for
each virtual channel. The output generated is composed of virtual channels to separate different streams to be
interleaved. Each virtual channel is identified by a unique channel identification number in the packet header.

8.3 Feature Description
The DS90UB964-Q1 provides a 4:2 hub for camera applications. The device includes 4 FPD-Link III inputs for
camera data streams from up to 4 serializers. The interfaces are compatible to DS90UB913AQ/913Q/933Q
serializers. Data received from the 4 input ports is aggregated onto one or two 4-lane CSI-2 interfaces.
