DC Operating Conditions & Specifications
DC Operating Conditions
Recommended operating conditions(Voltage referenced to VSS=0V, TA=0 to 70°C)
Notes: 1. VREF is expected to be equal to 0.5*VDDQ of the transmitting device, and to track variations in the DC level of the same. Peak-
to-peak noise on VREF may not exceed 2% of the DC value
2.VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to
VREF, and must track variations in the DC level of VREF
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
