3U VPX Virtex UltraScale+ FPGA board suits low-latency applications

Supporting rates up to 5.4 Gsamples per second and a DAC supporting rates up to 6Gsamples per second, both at 12 bits, the VPX570 is a low-latency RF ADC/DAC module from VadaTech.

The FPGA interfaces directly to rear I/O via SerDes and LVDS, supporting PCIe, SRIO, GbE/10GbE/40GbE or Aurora backplane connections. General purpose I/O signals, e.g. for trigger, are routed to the front panel that also contains eight LED/bi-colour. ADC and DAC have a common sampling clock, which can be fed from front panel (direct RF clock) or from PLL locked to a 10/100MHz reference clock sourced from front panel or backplane.

Sampling clock selection is by ordering option. The VPX570 includes platform health management/monitoring capability using VadaTech’s field-proven tier 2 platform management software.  An on-board management controller has the ability to access board sensors and manage FPGA image updates.

The unit is also available in a range of temperature and shock/vib specifications per ANSI/VITA 47, up to V3 and OS2.

The EV12DS460A and EV12AS350A both have parallel interfaces to the FPGA, avoiding latency associated with serialising/deserialising data. The XCVU13P FPGA has a large 360 Mbit on-chip UltraRAM which, with the ADC and DAC selection, makes this module suitable for low-latency applications such as DRFM, radar simulators and smart jammers, says VadaTech.
