Chapter 1: Cyclone IV Transceivers Architecture
Transceiver Architecture
1 The Cyclone IV GX device includes a hard intellectual property (IP) implementation
of the PCIe MegaCore® functions, supporting Gen1 Ã1, Ã2, and Ã4 initial lane widths
configured in the root port or endpoint mode. For more information, refer to âPCI-
Express Hard IP Blockâ on page 1â46.
Transceiver Architecture
Cyclone IV GX devices offer either one or two transceiver blocks per device,
depending on the package. Each block consists of four full-duplex (transmitter and
receiver) channels, located on the left side of the device (in a die-top view). Figure 1â1
and Figure 1â2 show the die-top view of the transceiver block and related resource
locations in Cyclone IV GX devices.
