The CFG1 and CFG2 pins can be used to adjust the TUSB1002A output voltage swing linear range and receiver equalization DC gain. Table 7-3 details the available options.
For best performance, the TUSB1002A should be operated within its defined VOD linearity range. The gain of the incoming VID should be kept 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 1200 mV, the maximum incoming VID signal at 5 GHz with a CHx_EQ[1:0] setting of 2 (5.5 dB) is 1200 x (10-(5.5/20)) = 637 mVpp. The TUSB1002A can be operated outside its VOD linear range but jitter will be higher.
