7.3.3.2 Limited VOD

Limited VOD mode is used to set the actual VOD level and is used when TUSB1104 is configured in limited redriver mode. In this mode the VOD is no longer a linear function of the input VID. For example, if the signal at TUSB1104's input (VID) is at 600 mVpp then the TUSB1104's output VOD will be around 1000 mVpp (assuming LINR_L3 is selected). The limited redriver mode is only supported on the SSRX1/2 transmitter. The TUSB1104 provides four different limited VOD settings. All four settings are available through register control.

Note:

Limited redriver mode is disabled by default and can only be enabled by setting the SSRX_LIMIT_ENABLE register. Once enabled, the VOD level for SSRX1/2 transmitters is controlled by the USB_SSRX12_VOD register
