Squelch Control
Controls electrical idle detect threshold level. Three levels are supported as shown in Table 1.
Beacon Support
With its broadband design, the SN65LVPE504 supports low frequency Beacon signal (as defined by PCIe 2.1
spec) used to indicate wake-up event to the system by a downstream device when in L2 power state. All
requirements for a beacon signal as specified in PCI Express specification 2.1 must be met for device to pass
beacon signals.
