Hi
During the symbol definition in my customer's CAD tool they found a mismatch in the pinout of ADS54T01IZAY.
See example below.
Pins G3 and G4 in the Figure 2 are NC but in the Table of pin assignments these pins are TRDYP/N.
This is just example and there are more cases like this.
Can you please advise if this is the correct pinout?
Hi Victor,
I will need to check with the author of this datasheet.
The latest datasheet revision history had P7 and N7 removed. I will update you on my finding.
Please also note that if the customer is not restricted to export control of the ADS54T01, they may use the ADS5401 which always output 12-bits. The ADS54T01 is mainly used in the China region where they have particular export control restrictions.
Hi Victor,
We are double checking the reason for the inconsistency. Somebody updated the datasheet to reflect this inconsistency.
It should be G3/G4 that was changed to NC.
Basically we have the ads54t02 (dual) and the ads54t01 (single). In the dual channel each adc has it’s own output bus and we duplicated the output flag signals (such as TRDY or HRES). For the single channel device we removed the pins (all unused LVDS outputs should be powered down).
Victor,
we have confirmed the following:
P7 and N7 are needed for the ADS54T01
G3 and G4 are *NOT* needed for the ADS54T01
The following are correct. Figure 2 need *no* update.
The following need update to P7 and N7
The following history should been “delete G4 and G3”.
