8 / 23 page 8 FN6981.1 November 19, 2009 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. FIGURE 1. DEVICE CHARACTERIZATION TEST SETUP FIGURE 2.
