Quartz RFSoC small form factor can be integrated into custom enclosures

Additions to the Quartz RFSoC architecture family, the Model 6350S and Model 6353S (Gen 3 RFSoC), eight-channel A/D and D/A converter sub-systems are supplied in a rugged small form factor package. The Model 6350S and Model 6353S are based on Pentek QuartzXM eXpress modules which use the Xilinx Zynq UltraScale+ RFSoC FPGA. The Model 6350S and Model 6353S are suitable for signal intelligent and communications intelligence (SigInt and ComInt), military communications, electronic warfare counter measures, radar transceiver, test and measurement, satellite comms (SatCom), lidar, 5G and LTE wireless applications.

The two sub-systems were developed by Pentek in response to Quartz RFSoC customers requesting challenging packaging options for the Pentek QuartzXM eXpress modules, revealed Bob Sgandurra, director of product management at Pentek.

“The small size of these subsystems enables customers to install our Quartz RFSoC technology within their existing enclosures,” he added.

The Model 6350S and Model 6353S are self-contained RF converter and processing sub-systems in a small mounting frame. Requiring only a single 12V power supply, the sub-systems can be integrated as a component in a larger system with minimal design effort, says Pentek. All analogue I/O and control and communication interfaces are accessible with industry standard connectors, simplifying connections to other system components. The bottom surface of the sub-system provides an efficient thermal interface enabling conduction cooling and allowing fanless operation in most installations.

The small Model 6350S and Model 6353S sub-systems are optimised for size, weight and power (SWaP). They measure 1.5 x 4.6 x 6.7 inches 38 x 117 x 170mm and weight 30oz or 850g. The sub-systems are intended for use in customer provided enclosures, and can be deployed in challenging and harsh environments.

The Pentek Quartz architecture embodies a streamlined approach to FPGA products, simplifying the design for reduced power and cost, while still providing some of the highest performance FPGA resources available today, says Pentek.

The sub-systems are supported by Pentek’s Navigator Design Suite tools. According to the company, Quartz products offer users an efficient path for developing and deploying software and FPGA IP for data and signal processing. The Xilinx Zynq UltraScale+ RFSoC processor integrates eight RF class A/D and D/A converters quad ARM Cortex-A53 and dual ARM Cortex-R5 processors into the Zynq FPGA fabric for multi-channel data conversion and processing on a single chip.

The front end of the Model 6350S (Gen 1 RFSoC) accepts analog IF or RF inputs up to 4GHz on eight coax connectors with transformer coupling to eight 4Gsamples per second 12-bit ADCs, delivering either real or complex DDC samples.  Additional IP-based decimation filters, provide overall DDC decimation from two to 128. Eight DACs accept baseband real or complex data streams from the FPGA’s programmable logic.

Each 6.4Gsample per second 14-bit DAC includes a digital upconverter with independent tuning and interpolations of 1x, 2x, 4x and 8x. All ADCs and DACs are transformer coupled to wideband coax cable connectors.

The Model 6353S (Gen 3 RFSoC) boosts the input signal bandwidth to 6GHz using a 5Gsample per second 14-bit ADC with additional decimation settings. The DAC rate increases from 6.4 to 10Gsamples per second.

The Model 6350S and Model 6353S support eight 28Gbit per second full duplex lanes using RFSoC GTY gigabit serial ports. With the built-in 100 GigE UDP interface or installation of a user provided serial protocol, this interface delivers a high speed Gbit data streaming path between the Model 6350S or Model 6353S and other identical sub-systems, optical transceivers, data storage or other processing systems.

The Model 635xS subsystems are pre-loaded with a suite of Pentek IP modules to provide data capture, timing, interface and processing for many common applications. Modules include DMA engines, DDR4 memory controllers, test signal and metadata generators, data packing and flow control.

The Navigator Design Suite for streamlined IP development includes: Navigator FDK (FPGA Design Kit) for custom IP and Navigator BSP (Board Support Package) for creating host software applications.

QuartzXM eXpress subsystems options for FPGA speed grade, and memory are in production now with delivery eight to 12 weeks after receipt of order.
