Description
The PCI598 is based on the AMD XCVP1902 VersalTM Premium Series FPGA, which provides over 6,800 DSP slices with total PL memory of 1116Mb and 8,460,288 LUTs. The FPGA interfaces to the quad QSFP-DD (Double Data Rate) modules. The card has a single DDR4 memory bank that is 64-bit wide with ECC for a total of 8GB and an additional two DIMM each 64-bit wide with ECC for total of 64GB. This allows for large buffer sizes to be stored during processing as well as for queuing the data to the host.
PCI598 has a PLL that can lock into an external clock such as 1PPS and/or to a sinewave clock up to 400MHz. The PCI598 could run as SyncE Master and/or Slave. The module provides clocks output which could be connected to adjacent PCI598 modules to allow synchronized between modules.
PCI598 has x16 PCIe edge connector routed to the FPGA PCIe hard IP block. The x16 SERDES going to the edge connector could be configured to run any protocol and integrated, for example, into VadaTech’s VT808 chassis. The x16 lanes could be bifurcated to dual x8 or quad x4 lanes. In addition, there are 16 uncommitted SERDES routed to a dual x8 expansion connector, providing direct connectivity to a neighboring FPGA (e.g. via Aurora, 10/40GbE, SRIO, PCIe) without the need to go through the host. Further the module has x24 LVDS pairs to a connector which could also be configured as two single ended signals per pair.
The Quad QSFP-DD cages could take 400/200/100Gb as well as 40Gb optical transceiver. Each optical module could be bifurcated to octal 1/10/25/58/112Gb lanes for a total of 32 ports (at 112Gb only 16 lanes are available). The optical modules are protocol agnostic and could take a mix of transceiver. The QSFP-DD modules are routed to the GTM transceivers on the FPGA which can operate at 1/20/25/58G/112G per lane. GbE RJ45 and USB 2.0 ports are also provided.
Active cooling of the module and option with passive cooling. The passive cooling requires a chassis that forces air over the PCI598 heat sink, such as VadaTech’s VT808 chassis.
