4 TMUX-8RQX-EVM Setup
1. The default setup of the board has all 8 generic pathways grounded, with the IC set to single supply
operation as the pad voltage is also set to ground. If dual operation is desired, then move to step 2. If not,
then move to step 3.
2. If dual supply operation is desired, then locate J9 on the EVM. Move the shunt so that the pins labeled
PAD
and
VSS
are shorted together instead of the default
PAD
to
VDD
connection. This will ensure the PAD of the
RQX package is exposed to the lowest potential in the system w.r.t. ground during dual supply operation.
3. All 8 generic signal pathway headers contain six pins.
and
show the generalized pinout
of the headers for the left and right side of the board respectively. Please note that the orientation is based
on J10 being on the top of the board.
