Notes:
• AC Capacitors required on RX lines on carrier board if connected directly to device. They are
not placed on the carrier board if connected to a PCIe connector. In that cases, the AC caps are
on the PCIe add-in board.
• See design guidelines for correct AC capacitor values.
• The PCIe REFCLK inputs and PCIEx_CLK clock outputs comply to the PCIe CEM specification
“REFCLK DC Specifications and AC Timing Requirements.” The clocks are HCSL compatible.
