GENERAL DESCRIPTION
The AD2S1200 is a complete 12-bit resolution tracking resolverto-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.
