Voltage
The data-input transition time is controlled by a 4th-order Bessel filter with f
2.667Gbps and below. The f
Supply current is measured with unterminated outputs or with AC-coupled output termination (see Figure 1).
Between sensitivity and overload, all AC specifications are met and the output is 0.95 x limited output amplitude.
Guaranteed by design and characterization.
The deterministic jitter (DJ) caused by the input filter is not included in the DJ generation specification.
The PRBS 2
Random jitter was measured without using a filter at the input.
The signal at the input is switched between two amplitudes, Signal_ON and Signal_OFF, as shown in Figure 2A.
The signal at the input is switched between 1.2V
