Note 1:
An interfering signal (2
15 - 1 PRBS, B3ZS encoded, compliant waveshape, nominal bit rate) is added to the input signal. The
combined signal is passed through 0 to 900 feet of coaxial cable and presented to the DS325x receiver. This spec indicates the
lowest signal-to-noise ratio that results in a bit error ratio
≤10-9.
Note 2:
Not tested during production test.
Note 3:
Measured on the line side (i.e., the BNC connector side) of the 1:2 receive transformer (Figure 2-1). During measurement,
incoming data traffic is unframed 2
15 - 1 PRBS.
Note 4:
With respect to nominal 800mVpk signal.
