Note 4:
Between sensitivity and overload, all AC specifications are met.
Guaranteed by design and characterization.
The deterministic jitter caused by this filter is not included in the DJ generation specifications (input).
2
23
- 1 PRBS pattern was substituted by K28.5 pattern to determine the high-speed portion of the deterministic jitter. The
low-speed portion of the DJ (baseline wander) was obtained by measuring the eye width difference between outputs gen-
erated using K28.5 and 2
23
- 1 PRBS patterns.
Random jitter was measured without using a filter at the input.
The supply current measurement excludes the CML output currents by connecting the CML outputs to a separate V
CC
(see Figure 1).
Unless otherwise specified, the pattern for all LOS detect specifications is 2
23
- 1 PRBS.
The signal at the input is switched between two amplitudes, Signal_ON and Signal_OFF, as shown in Figure 2.
I
CM_INPUT
is the input common mode. I
RSSI
is the current at the RSSI output.
Note 10:
Stability is defined as variation over temperature and power supply with respect to the typical gain of the part.
