This single-ended NRZ Data input is capacitively AC coupled to an internal line receiver.
The slew rate (10% to 90%, 90% to 10%) of the input data should not fall below 2 ns.
Data rates, minimum and maximum
Minimum:
100 Mb/s
Maximum:
1.4 Gb/s
These data rates are the limits of the External Data Input to receive externally supplied
NRZ Data (within level specifications with the longest consecutive pattern of 1s and 0s
not more than seven) and to then pass this serial data as a differential 75
signal into
the GBIC receTX_DATA and –Tx_DATA signal paths without significant RC time
constants being imposed on the data sequence.
Maximum nondestructive DC voltage
10 V
This is the maximum nondestructive DC potential that can be applied to this capacitively-
coupled input.
Maximum nondestructive AC input voltage
swing
5 V
p-p
This is the maximum nondestructive AC voltage swing that can be applied to this
capacitively coupled input; the input 50
termination can be damaged above this level.
Jitter Transfer
This DATA Input is digitally compared and then sent directly to the GBIC receptacle
"
Tx_DATA pins as a differential signal input; no significant timing jitter is added nor
subtracted from that which is inherent in the external DATA Input signal.

Typical:
5.0 V
This single-ended clock input is capacitively AC coupled to an internal line receiver. The
slew rate (10% to 90%, 90% to 10%) of the input data should not fall below 300 ps.
Maximum non-destructive AC input voltage
swing (typical)
5.0 V peak-peak
The maximum non-destructive AC voltage swing that can be applied to this capacitively
coupled input; the input 50-ohm termination is damaged above this level.
