Note 1:
The data-input transition time is controlled by a 4th-order Bessel filter with f-3dB = 0.75 x 2.667GHz for all data rates of
2.667Gbps and below. The f-3db = 0.75 x 3.2GHz for a data rate of 3.2Gbps.
Note 2:
Supply current is measured with unterminated outputs or with AC-coupled output termination (see Figure 1).
Note 3:
Between sensitivity and overload, all AC specifications are met and the output is 0.95 x limited output amplitude.
Note 4:
Guaranteed by design and characterization.
Note 5:
The deterministic jitter (DJ) caused by the input filter is not included in the DJ generation specification.
Note 6:
The PRBS 223 - 1 equivalent pattern consists of a K28.5 pattern plus 240 ones plus K28.5 pattern plus 240 zeros.
Note 7:
Random jitter was measured without using a filter at the input.
Note 8:
The signal at the input is switched between two amplitudes, Signal_ON and Signal_OFF, as shown in Figure 2A.
Note 9:
The signal at the input is switched between 1.2VP-P and Signal_OFF as shown in Figure 2B.
Note 10: VTH is the voltage at pin 5 referenced to VCC (see Figure 5).
