Hi Champs,
In the datasheet of DS90UB953, suggested resister value is written in Table 7 and Table 11, for Mode Select and IDx configuration respectively.
Customer wants to use 390 ohm of E24 series resister(+/- 5%) for Rlow.
In this case, RATIO MIN = 0.035 and RATIO MAX = 0.04, still in range of “Synchronous” mode.
Q.1) Is it feasible with above resister selection?
Also for IDx configuration, customer wants to use 39k ohm of E24 series resister.
But IDX=1 case, Rhigh is open.
How can we calculate RATIO_MIN/MAX with Rlow resister value?
Best regards,
