OPTIMAL CABLE BOOST SETTINGS
The settable equalizing filter within the QLx4600 enables the device to optimally compensate for frequency-dependent attenuation across a
wide variety of channels, data rates, and encoding schemes. For the reference channels plotted in Figure 3, Table 10 shows the optimal
boost setting when transmitting a PRBS-7 signal. The optimal boost setting is defined as the equalizing filter setting that minimizes the output
residual jitter of the QLx4600. The settings in Table 10 represent the optimal settings for the QLx4600C across an ambient temperature range
of 0ºC to 70ºC. The optimal setting at room temperature (20ºC to 40ºC) is generally one to two settings lower than the values listed in Table
10.
Note 1: Optimal boost settings should be determined on an application-by-application basis to account for variations in channel type, loss characteristics, and
encoding schemes. The settings in Table 9 are presented as guidelines to be used as a starting point for application-specific optimization.
