Интерфейсные элементы - Буферы и повторители сигналов SN65LVPE501RGET

PCI и PCIe устройство , PCIe редрайвер/выравниватель, PCIe 2.1, питание 3В до 3.6В, VQFN-24

The SN65LVPE501RGET is a 2-channel x1 PCI Express Gen II Redriver/Equalizer supporting data rates of up to 5Gbps. The device complies with PCIe spec revision 2.1. 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 compensate 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 de-emphasis 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.

• Support for both PCIe Gen I (2.5Gbps) and Gen II (5.0Gbps) speed
