Notes:
1. When using the on-chip clock divider, a minimum input clock slew rate of 30 mV/ns is required.
2. HCSL measurements were made with receiver termination. See Figure 9 on page 19.
3. Output to Output skew specified for outputs with an identical configuration.
4. Defined as skew between any output on different devices operating at the same supply voltage, temperature, and and
equal load condition. Using the same type of inputs on each device, the outputs are measured at the differential cross
points.
5. Measured for 156.25 MHz carrier frequency. Sine-wave noise added to VDDOX (3.3 V = 100 mVPP) and noise spur
amplitude measured. See “AN491: Power Supply Rejection for Low-Jitter Clocks” for further details.
