define their own operation. With ispLEVER, the user can define the mode for each quad in a design. Nine modes
are currently supported by the ispLEVER design flow:
• 8-bit SERDES Only
• 10-bit SERDES Only
• SONET (STS-12/STS-48)
• Gigabit Ethernet
• Fibre Channel
• XAUI
• Serial RapidIO
• PCI-Express
• Generic 8b10b
flexiPCS Quad
The flexiPCS logic is arranged in quads containing logic for four independent full-duplex data channels. Each
device in the LatticeSC family has up to eight quads of flexiPCS logic. The LatticeSC Family Selection Guide table
on the first page of this data sheet contains the number of flexiPCS channels present on the chip. Note that in
some packages (particularly lower pin count packages), not all channels from all quads on a given device may be
bonded to package pins.
Each quad supports up to four channels of full-duplex data and can be programmed into any one of several proto-
col based modes. Each quad requires its own reference clock which can be sourced externally or from the FPGA
logic. The user can utilize between one and four channels in a quad, depending on the application.
Figure 2-30 shows an example of four flexiPCS quads in a LatticeSC device. Quads are labeled according to the
address of their software controlled registers.
