The AD2S1200 is a complete 12-bit resolution tracking resolver-
to-digital converter, integrating an on-board programmable
sinusoidal oscillator that provides sine wave excitation for
resolvers. An external 8.192 MHz crystal is required to provide
a precision time reference. This clock is internally divided to
generate a 4.096 MHz clock to drive all the peripherals.
The converter accepts 3.6 V p-p ± 10% input signals, in the
range of 10 kHz to 20 kHz on the Sin and Cos inputs. A Type II
servo loop is employed to track the inputs and convert the input
Sin and Cos information into a digital representation of the
input angle and velocity. The bandwidth of the converter is set
internally to 1.7 kHz with an external 8.192 MHz crystal. The
maximum tracking rate is 1,000 rps.
