SN65DPHY440SS: How to adjust the driving ability of each channel output

Part Number: SN65DPHY440SS

We use this IC, the voltage of VOD0 and VOD1 is too low, so we want to improve it by adjusting the driving ability.

    Hi,

    You can use the VSADJ_CFG0 to control output voltage swing for DB HS transmitters and the LP TX rise and fall times. Pin state is sampled on the rising edge of RSTN. Refer to Table 3 for details on voltage swing settings based on this pin and PRE_CFG1 sampled state.

    VIL = 200 mV or 220 mV based on PRE_CFG1 sampled state.

    VIM = 200 mV typical

    VIH = 220 mV typical

    Thanks

    David
