1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged
exposure to levels above the operating limits but below the Absolute Maximums may affect device reliability.
2. Rising edge of ICLK compared with rising edge of CLK2, with FBCLK connected to FBIN, and 15 pF load on CLK2.
See the graph on page 4 for skew versus frequency and loading.
