VadaTech has announced the VPX570. The VPX570 is a low latency RF ADC/DAC module withADC supporting rates up to 5.4 GSPS and a DAC supporting rates up to 6 GSPS, both at 12 bits. The EV12DS460A and EV12AS350A both have parallel interfaces to the FPGA, avoiding latency associated with serialising/deserialising data. The XCVU13P FPGA has a large 360Mb 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.
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 8 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.
