Notes:
1. V
REF
is expected to equal V
CC/2
of the transmitting device and to track variations in the DC level of the same. Peak-to-peak noise on V
REF
may not exceed +/-1 percent of the DC
value. Peak-to-peak AC noise on V
REF
may not exceed +/-2 percent of V
REF
. This measurement is to be taken at the nearest V
REF
bypass capacitor.
2. V
TT
in sot applied directly to the device. V
TT
is a system supply for signal termination resistors, is expected to be set equal to V
REF
and must track variations in the DC level of V
