Note 1:
Measured on the line side (i.e., the BNC connector side) of the 2:1 transmit transformer (Figure 2-1).
Note 2:
Unframed all ones output signal, 3 kHz bandwidth, cable length 225 feet to 450 feet.
Note 3:
Measured with jitter-free clock applied to TCLK and a bandpass jitter filter with 10Hz and 800kHz cutoff frequencies. Not tested
during production test.
