system with the WRPC, presuming the existing project already includes an
|
|
|
appropriate FPGA and the required environment (power supply,

|
configuration etc.). WRPC has been successfully tested with GTP and GTX
|
|
|
transceivers of Xilinx's FPGAs (e.g. Spartan-6 LXT family). Support for

Altera GX PHYs is currently being implemented.

The necessary external components are the fiber optic transceiver (SFP
|
|
|
module) and two digitally tunable clock generators (one for the main
|
|
|
PLL, one for producing the DMTD offset frequency). The remaining blocks
|
|
|
outside the FPGA are optional and their use depends on the particular
|
|
|
application: An optional I2C interface is provided for attaching an
|
|
|
external EEPROM, which can store the device's configuration data (MAC
|
|
|
address and calibration parameters).
