DDR I/DDR II Phase Lock Loop Zero Delay Buffer

Notes:
1. Unused inputs must be held high or low to prevent them from floating.
2. DC input signal voltage specifies the allowable DC execution of differential input.
3. Differential inputs signal voltages specifies the differential voltage [VTR-VCP] required
for switching, where VTR is the true input level and VCP is the complementary input
level.
4. Differential cross-point voltage is expected to track variations of V
DD
and is the voltage
at which the differential signal must be crossing.
