Notes for Table 18

Unused differential input ports should be left floating and set in LVDS mode, or the positive and negative inputs tied to

VDD and GND respectively.

Note 1. Assuming a differential input voltage of at least 100 mV.

Note 2. Unused differential input terminated to VDD-1.4 V.

Note 3. With 50 ! load on each pin to VDD-2 V . i.e. 82 ! to GND and 130 ! to VDD.
