The CFG1 and CFG2 pins can be used to adjust the TUSB1002A output voltage swing linear range and receiver equalization DC gain. Table 6-3 details the available options.
For best performance, make sure to operate the TUSB1002A within the defined VOD linearity range. Keep the gain of the incoming VID to less than or equal to the TUSB1002A VOD linear range setting. The can be determined by Equation 1:
where
For example, for a VOD linearity range setting of 1200mV, the maximum incoming VID signal at 5GHz with a CHx_EQ[1:0] setting of 2 (5.5dB) is 1200 x (10-(5.5/20)) = 637mVpp. The TUSB1002A can operate outside VOD linear range, but the jitter will be higher.
