Hi,

For AC coupling and device decoupling we use either X5R or X7R dielectrics a general purpose ceramic capacitor will work fine across the full industrial temperature range.

I typically recommend using capacitor body sizes that are small to reduce PCB layout issues with impedance control. For this device I would recommend using 0402 size capacitors or smaller.

I recommend the SN75LVPE801 only for SATA applications. For PCIe applications please look at the DS80PCI102 or DS125BR111.

Regards,

Lee

I understand the capacitor type.
Used with PCIe Gen2 and 3.
Since there are many channels, I want to use SN75LVPE801 in consideration of the price.
Software setting is also troublesome.
Is SN75LVPE801 NG?

For more channels we have the DS80PCI402, DS80PCI800, or DS80PCI810. There is also a 4 channel device DS160PR410.

All of these devices can be configured with pin settings or EEPROM download at power-up.

Some new PCIe systems will not detect the LVPE801 device.

Lee
