4 EQ vs. BOOST Pins

TUSB216I BOOST function combines the TUSB212 EQ (AC Boost) and DC Boost functionality into one setting. The ideal TUSB216I BOOST setting is dependent upon the signal chain loss characteristics of the target platform. The recommendation is to start evaluation with BOOST level 0, and then increment to BOOST level 1, and so on. For the TUSB216I to recognize any change to the BOOST pin setting, the RSTN pin must be toggled.

Please note that the optimal EQ level on a TUSB212 implementation will not necessarily be the optimal BOOST setting for a TUSB216I implementation.

For both devices, pin 6 is sampled after Power-On Reset or de-assertion of the RSTN pin.
