Using the EVM with the DUT at 3.3 V or lower
When the TL16C750E device needs to be tested at lower than 3.3 V, the jumper at J29 should be
removed and a power supply can be connected to J10 instead. J31 should also include a shunt from
position 1 and 2 where the board denotes
if VUART
≤
3V6
. J30 should be shunted from position 2 and 3
where the board denotes if
VUART
≤
3V6
. Jumpers denoted as J9, J25, J29, J24, and J19 should not
have shunts.
provides example.
Figure 5. DUT below 3.3 V
If used at 3.3 V, the configuration mention above can be used with the power supply set to 3.3 V or J29
can be shunted to positions 2 and 3 so that the onboard LDO can be used. The 5 V input should be used
in this instance as well to power the LDO but J10 would be removed if the 5 V input is to be used. The
jumper positions described previously and in
still apply.
