Other Parts Discussed in Thread: TUSB212,
Our original material uses TUSB212. After changing the PIN to PIN to TUSB216, the eye diagram test becomes very poor. Checking the specifications shows that the power supply specifications are different, but the jumper is changed to 5V. The eye diagram test of TUSB216 has not improved. The motherboard design is 3.3V power supply, and the eye diagram test effect under 3.3V power supply needs to be solved
