The device plies with PCIe spec revision 2.1. Programmable EQ, De-Emphasis and Amplitude Swing The SN65LVPE501 is designed to minimize the signal degradation effects such as crosstalk and inter-symbol interference (ISI) that limits the interconnect distance between two devices. The input stage of each channel offers selectable equalization settings that can be programmed to match loss in the channel. The differential outputs provide selectable de-emphasis to pensate for the anticipated distortion PCIe signal will experience. Level of de-emphasis will depend on the length of interconnect and its characteristics. Both equalization and deemphasis levels are controlled by the setting of signal control pins EQ1, EQ2 and DE1, DE2. To provide additional control of signal integrity in extended backplane applications LVPE501 provides independent output amplitude control for each channel. See Table 2 for setting details. Device Power On Device initiates internal power-on reset after VCC has stabilized. External reset can also be applied at anytime by toggling RST pin. External reset is remended after every device power-up. When RST is driven high, the device samples the state of...
