Typical Performance Characteristics
VDD = 1.2V, TA = +25°C, unless otherwise noted. Performance was characterized using the system testbed shown in
Figure 1. Unless otherwise noted, the transmitter generated a non-return-to-zero (NRZ) PRBS-7 sequence at 800mVP-P
(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 2. 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.
