The device features fully differential clock paths to minimize both device and system skew. The AZ100LVE310 offers two selectable clock inputs allowing redundant or test clocks to be incorporated into the system clock trees. The AZ100LVE310 provides a VBB output for single-ended use or a DC bias reference for AC coupling to the device. For single–ended input applications, the VBB reference should be connected to one side of the CLKa/CLKb differential input pair. The input signal is then fed to the other CLKa/CLKb input. The VBB pin should be used only as a bias for the AZ100LVE310 as its current sink/source capability is limited. When used, the VBB pin should be bypassed to ground via a 0.01μF capacitor. Both sides of the differential output must be terminated into 50Ω to ensure that the tight skew specification is met, even if only one side is used. In most applications all eight differential pairs will be used and therefore terminated. In the case where fewer than eight pairs are used, all output pairs on the same package side (sharing the same VCCO) as the pairs being used should be terminated to maintain minimum skew. Failure to do this will result in small degradations of propagation delay (on the order of 10–20ps) of the outputs being used; while not being catastrophic to most designs this will result in an increase in skew. NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.

The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal. The within-device skew is defined as the worst-case difference between any two similar delay paths within a single device. VPP is the minimum peak-to-peak differential input swing for which AC parameters are guaranteed. The VPP(min) is AC limited for the LVE310, because differential input as low as 50 mV will still produce full ECL levels at the output. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level must be such that the peak-to-peak voltage is less than 1.0V and greater than or equal to VPP(min).
