  We present a silicon drift detector (SDD) system for the spectroscopy
focusing array (SFA) of the enhanced X-ray timing and polarimetry (eXTP)
mission. The SFA focuses on fast timing (time resolution below 10 {\mu}s) and
good spectroscopy capabilities (energy resolution better than 180 eV @ 6 keV).
The sensor, consisting of 19 hexagonally shaped pixels with a total sensitive
area of ${5.05}\, cm^{2}$, is connected to three high time resolution
spectroscopy (HTRS) ASICs, allowing a fast readout of the detector signals. The
detector works in a Charge- Sensitive Amplifier configuration. We assembled a
prototype detector module and present here its mechanical design, describe the
used sensor, and report about its performance.
