Notes 1. V
REF
is expected to be equal to 0.5* V
DDQ
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 2% of the DC value.
3.
V
TT
is not applied directly to the device. V
TT
is 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
REF
.
3.
V
ID
is the magnitude of the difference between the input level on CLK and the input level on CLK .
