| Standard PCS |
- Operates at a data rate up to
12.5
Gbps
- Supports protocols such as
PCI-Express, CPRI 4.2+, and GigE
- Implements other protocols using Basic/Custom (Standard PCS)
transceiver configuration rules.
|
| Enhanced PCS |
- Performs functions common to most serial data industry
standards, such as word alignment, encoding/decoding, and
framing, before data is sent or received off-chip through the
PMA
- Handles
data transfer to and from the FPGA fabric
- Handles
data transfer internally to and from the PMA
- Provides frequency compensation
- Performs channel bonding for multi-channel low skew
applications
|
| PCIe Gen2 PCS |
- Supports the seamless switching
of Data and Clock between the Gen1 and Gen2 data rates
- Provides support for PIPE 3.0 features
- Supports the PIPE interface with the Hard IP enabled, as well
as with the Hard IP bypassed
