Notes:
1. For clock division applications, a minimum input clock slew rate of 30 mV/ns is required.
2. See Figure 4.
3. Defined as skew between outputs on different devices operating at the same supply voltages, temperatures, and equal
load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
4. Measured for 156.25 MHz carrier frequency. Sine-wave noise added to V_DDOX (1.8V=50mV_PP, 2.5/3.3V=100mV_PP)
and noise spur amplitude measured. See AN491 for further details.
