The Alveo U55C data center accelerator card hosts two small form-factor pluggable (QSFP) connectors that accept optical and copper modules. Each connector is housed within a single cage assembly and are accessible through the I2C interface.
Access from the FPGA to QSFP modules and support for miscellaneous QSFP signals is provided through the satellite controller. For more information about the QSFP module, see QSFP Specification.
- MGTREFCLK0 is from SI5394 with programmable output frequencies
- Maximum QSFP power is 3.5W per port
- The target for QSFP channel length is 4 inches maximum
Detailed FPGA connections for this feature are documented in the Alveo U55C data center accelerator card XDC file.
