Note 1:
Between sensitivity and overload, all AC specifications are met.
Note 2:
Guaranteed by design and characterization.
Note 3:
The deterministic jitter caused by the filter is not included in the DJ generation specification.
Note 4:
Random jitter was measured without using a filter at the input.
Note 5:
The supply current measurement excludes the CML output currents by connecting the CML outputs to a separate V
CC
. (See
Figure 1.)
Note 6:
Hysteresis is calculated as 10 log (V
DEASSERT
/ V
ASSERT
). Unless otherwise specified, the data rate for all LOS detect speci-
fications varies from 622Mbps up to 3.2Gbps, and the patterns are 1010 or 2
23
- 1 PRBS.
Note 7:
The signal is switched between two amplitudes, Signal_On and Signal _Off as shown in Figure 2.
Note 8:
I
CM_RSSI
is the input common-mode current. I
RSSI
is the current at the RSSI output.
Note 9:
Stability is defined as the variation over temperature and power supply with respect to the typical gain of the part.
