6.3.3.1 Linearity VOD

Linearity VOD defines the linearity range of the TUSB1004. When TUSB1004 is in linear VOD mode, the output VOD is a linear function of the input VID. For example, if the signal at TUSB1004's input (VID) is at 600 mVpp then the TUSB1004's output VOD will be around 600 mVpp. Linearity VOD mode is the default operation of the TUSB1004. Linear VOD mode is supported on SSRX1/2 and CTX1/2 transmitters.

The TUSB1004 provides four different linearity VOD settings. All four settings are available in I2C mode through register control. In pin-strap mode, the linearity is fixed at the highest setting.
