could anyone provide a layman's understanding of what FPGA DAC means?

Background
Redefining sonic performance in the affordable DAC category, the Qute EX showcases the unique talents of Robert Watts, whose state-of-the-art world-class proprietary FPGA technology lies at the digital heart of the device and allows capabilities far exceeding that of normal commercial DACs. The custom-designed FPGA (Field Programmable Gate Array) incorporates all of the functions required of a DAC: SPDIF decoding; Isochronous USB timing and Digital PLL; WTA interpolation filtering; DSD over USB support and finally, the Pulse Array DAC.
The ‘HD’ USB input benefits from its own separate FPGA and features asynchronous USB technology, isolating the digital clocks from the computer. Each sample rate clock is generated discretely using highly accurate crystal oscillators for optimum performance and ultra-low jitter performance.
The Qute EX shares the same bomb-proof build quality and stunning aesthetics that have helped make Chord Electronics famous around the world, and just like other members of the Chordette range, the QuteEX benefits from a one-piece aluminium chassis that has been milled from solid billet in the UK. Complementing the elegant design is a top-mounted ‘porthole’ that gives users an intriguing insight into the internal circuitry, which changes colour with differing incoming sample rates.
Exceptional sound quality has been achieved by our highly accomplished engineering team, thanks to their world-renowned expertise with D/A conversion and DAC production. Like all Chordette boutique products, the Qute EX can be complemented with a matching rack or Chordette Carry case.
An upgraded DAC will also be added to our four-strong Chordette X Series, replacing the QX DAC. Called the QEX, it will join the IX streamer, TX headphone amp and SX power amp to complete the X Series which features squared-off casework and a number of luxurious finishes, including highly polished gold.
