Reference Resistor Connection. An off-chip 4.75kΩ ±1%
resistor is connected between the positive resistor reference
pin RES and a Kelvin ground contact RESK for the APS port
LVDS reference. An on-chip negative feedback path will force
the 1.20V VREF voltage onto RES, therefore forcing 252µA of
current to flow through the resistor.
Analog
RESK is electrically connected to AVSS within the block, but
should not be connected to AVSS, either on-chip or off-chip.
