DC Operating Conditions & Specifications
DC Operating Conditions
Recommended operating conditions(Voltage referenced to VSS=0V, TA=0 to 70°C)
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
2.V
TT
is not 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
REF
3. V
ID
is the magnitude of the difference between the input level on CK and the input level on CK.
