TYPICAL PERFORMANCE CHARACTERISTICS
V
otherwise noted, the transmitter generated a non-return-to-zero (NRZ) PRBS-7 sequence at 800mVpp (differential) with 10ps of peak-to-peak
deterministic jitter. This transmit signal was launched into twin-axial cable test channels of varying gauges and lengths. The loss
characteristics of these test channels are plotted as a function of frequency in Figure 3. The received signal at the output of these test
channels was then processed by the QLx4600-SL30 before being passed to a receiver. Eye diagram measurements were made with 4000
waveform acquisitions and include random jitter.
