SNLS500 – JULY 2016
8.4 Device Functional Modes
DS90UB964-Q1 operating modes:
• RAW10 (DS90UB913AQ/913Q/933Q compatible)
• RAW12 LF (DS90UB913AQ/913Q/933Q compatible)
• RAW12 HF (DS90UB913AQ/913Q/933Q compatible)
The modes control the FPD-Link III receiver operation of the device. In each of the cases, the output format for
the device is CSI-2 via one or two CSI-2 transmit ports.
Each port can be individually configured for RAW modes of operation.
The DS90UB964-Q1 includes forwarding control to allow multiple video streams from any of the received ports to
be mapped to either of the CSI-2 ports.
The input mode of operation is controlled by the FPD3_MODE (Register 0x6D[1:0]) setting in the Port
Configuration register. The input mode may also be controlled by the MODE strap pin.
8.4.1 RAW Mode
In Raw mode, the DS90UB964-Q1 receives RAW10 or RAW12 data from a DS90UB913AQ/913Q/933Q
serializer. The data is translated into a RAW10 or RAW12 CSI-2 video stream for forwarding on one of the CSI-2
transmit ports. For each input port, the CSI-2 packet header VC-ID and Data Type are programmable.
8.4.2 MODE Pin
Configuration of the device may be done via the MODE input strap pin, or via the configuration register bits. A
pullup resistor and a pulldown resistor of suggested values may be used to set the voltage ratio of the MODE
input (V_R2) and V_DD18 to select one of the 6 possible selected modes. Possible configurations are:
• FPD-Link III Coaxial or STP
• 12-bit LF / 12-bit HF / 10-bit DVP modes (DS90UB913AQ/913Q/933Q compatible)
