Curtiss-Wright launches high bandwidth/high resolution platform for DRFM in defense and aerospaceCurtiss-Wright Controls Defense Solutions claims their CHAMP-WB (WideBand) is the industry’s first Xilinx Virtex-7 OpenVPX COTS DSP Engine designed for sense-and-response applications that require high bandwidth and minimal latency. Curtiss-Wright is also introducing its first module for the CHAMP-WB, the TADF-4300, featuring Tektronix Component Solutions’ 12.5 GS/s Analog-to-Digital (ADC) and /Digital-to-Analog (DAC) technologies.
Combined, these two modules form the CHAMP-WB-DRFM and according to the company provide the highest bandwidth/highest resolution platform for wideband Digital Radio Frequency Memory (DRFM) processing available in the embedded defense and aerospace market, delivering 12.5 GS/s 8-bit ADC and 12.5 GS/s 10-bit DAC performance from a single 6U slot.
The CHAMP-WB couples the dense processing resources of a single large Virtex7 FPGA with two high-bandwidth enhanced FMC mezzanine sites on a rugged 6U OpenVPX (VITA 65) form factor module. The board’s data plane connects directly to the FPGA with support for Gen2 Serial RapidIO (SRIO) data plane fabric. Alternate fabrics can also be supported with different FPGA cores. A Gen3 PCI Express (PCIe) switch connected to the board’s expansion plane enables a single host card, such as Curtiss-Wright’s VPX6-1957 or CHAMP-AV8 to control multiple CHAMP-WB cards without utilizing data-plane bandwidth.
The CHAMP-WB features two high-bandwidth FMC sites that have been enhanced with an auxiliary connector to provide additional I/O capability. Twenty back-plane SERDES links, which can operate up to 10.3 Gbps, and 16 LVDS pairs provide additional I/O capability.
The TADF-4300 module supports sampling in the 2nd nyquist zone, to analyze signals up to 8 GHz and provides sub-30 ns latency for the ADC and sub 10ns for the DAC. Spurious Free Dynamic Range varies over frequency, and is >58 dB up to 3 GHz and decreases to 45 dB from 3 GHz to 6 GHz signal input frequency. ENOB varies linearly from 7.2 at low frequency, 6.5 at 3 GHz and 6.2 at 6 GHz.
