Logic-X claims FMC offers best-in-class low latency, high speed

Providing 5.4Gsamples per second data acquisition at 12-bits resolution, the LXD30K0 module is available from Logic-X in an FMC form factor.

The adaptable compute acceleration platforms (ACAP) and sensor processing module specialist offers the LXD30K0 low latency, wide bandwidth analogue interface FPGA mezzanine card (FMC) module for electronic warfare systems, radar waveform generators and receivers and advanced digital radio frequency memory (DRFM) applications as well as medical and telecommunications systems.

The LXD30K0 uses an ADC (EV12AS350A) and DAC (EV12DS460) from Teledyne e2v for the analogue input and output stages. Its 5.4Gsamples per second data sampling at 12-bits resolution, contributes to what is claimed to be a best-in-class signal to noise ratio (SNR). It is also claimed to delivers “unmatched performance” in relation to spurious free dynamic range (SFDR), close-in phase noise. Latency is just 7.2 nanoseconds on the analogue input and 1.2 nanoseconds on the analogue output. The use of LVDS connectivity to the host carrier also delivers a low latency from the RF input to the RF output; this can be less than 18 nanoseconds depending on the carrier used.

The LXD30K0’s analogue input stage also features a very wide bandwidth of 0.5MHz to 4.8GHz with sampling at 5.4Gsamples per second generating an instantaneous bandwidth of 2.7GHz. The output bandwidth ranges from 0.5MHz to 6GHz and the instantaneous output bandwidth is 1.35GHz at a sampling data rate of 5.4Gsamples per second. There is a flexible clock tree which generates a very clean, low jitter and low phase clock that is distributed to the ADC and DAC. External synchronisation trigger input ensures easy integration into single channel systems as well as standalone operation. For larger systems, it is possible to directly provide the sample clock to the front panel SSMC connector or to synchronise the local clock generator to an external reference clock.

The LXD30K0 also features significant power saving options and advanced power/health monitoring capabilities.  Multi-card synchronisation also enables multiple input, multiple output systems to be built. The FMC form factor suits both the development of new systems and enables existing host carrier systems to be easily upgraded, says Logic-X. The LXD30K0 is compliant with both the VITA 57.1 and VITA 57.4 FMC standards.
