Other Parts Discussed in Thread: TIDEP0040
Hello,
My customer has a question about Vref pin in TFP410.
[Q]
They want to configure Vref pin as high-swing 3.3V input signal level.
Which is your recommendation among this ?
(A) D/S P.5 Pin Functions : "For high-swing 3.3-V input signal levels, VREF should be tied to VDD."
(B) D/S P.27 Figure 33 : VREF pulls up with 33k ohm.
(C) TIDEP0038, TIDEP0040 (TI Reference Design) : VREF pulls up with 510 ohm.
Best Regards,
Hiroshi Katsunaga
