STEVAL-IPE011V1
common clock with programmable frequency to
all the daughterboards.
The presence of dedicated networks greatly
reduces the sampling (aliasing) noise and the
crosstalk noise between voltage and current
channels, increasing meter precision. The
STPMS1 produces a sigma-delta stream, sent
together with the supply voltage, to the STPMC1
through a card edge connector.
The motherboard receives the sigma-delta
streams from the daughterboards which are
further elaborated by the STPMC1. This device,
from a 4.194 MHz crystal oscillator, provides a
