4 port Signal Interface
G.703, 2,048 kbits/s * 4
Signal Characteristics
Pulse shape:
:
As ITU-T G.703 pulse mask
Line code:
HDB3
Data type
:
G.704 framed or unframed
Input sensitivity
:
-13.6dB
Nominal amplitude:
:
±3.00 V, 120 interface
Loss of Input Signal Threshold::300 mV
Data Decision Threshold:43% to 57% peak
Input Pulse Width:
230 ns to 260 ns
Output Pulse Width:
244 ±20 ns (at mid level)
Input / Output Impedance
120 /75 balanced
selectable high-impedance input (40 k )
Input / Output Jitter Attenuation
45 dB at 40 kHz (typical)
20 dB / decade attenuation above the 10 kHz corner
frequency
Jitter attenuation is applied to the input signal for input data
transfers and to the output signal when the input signal is used
as an external clock reference for output data transfers.
Input jitter tolerance
1200 UI at 10 kHz
14 UI at 750 Hz
0.4 UI at 10 kHz – 100 kHz
