Notes:
1. Measured from the V
CC
/2 of the input to the differential output crossing point
2. Defined as skew between outputs at the same supply voltage and with equal load condition. Measured at the outputs differential crossing point.
3. Defined as skew between outputs on different parts operating at the same supply voltage and with equal load condition. Measured at the out-
puts differential crossing point.
4. All parameters are measured at 500MHz unless noted otherwise
