5.4.22.1 External FrameSync Control

In External FrameSync mode, an external signal is input to the DS90UB964-Q1 through one of the GPIO pins on the device. The external FrameSync signal can be propagated to one or more of the attached FPD3 Serializers through a GPIO signal in the back channel.

GUID-9E754942-61BB-49B1-ACC1-E6EC0B221325-low.gifFigure 5-15 External FrameSync

Enabling the external FrameSync mode is done by setting the FS_MODE control in the FS_CTL register to a value between 0x8 (GPIO0 pin) to 0xF (GPIO7 pin). Set FS_GEN_ENABLE to 0 for this mode.

To send the FrameSync signal on the BC_GPIOx signal of an FPD-Link port, the BC_GPIO_CTL0 or BC_GPIO_CTL1 register can be programmed for that port to select the FrameSync signal.
