We are working on using ADAS1000-4 and ADAS1000-2 in gang mode for ECG data capture. We would like to feed clock using clock generator instead of Oscillator. Should we connect the clock to Clock_IO Pin or XTALin pin.
In the ECGCTL register Bit 6 (CLKEXT), there is option to select either XTLA as clock source or Clock_IO as clock Source. Please clarify, if we can connect clock signal from a clock generator to Clock_IO pins of both ADAS1000-4 and ADAS1000-2 IC.
or do we need to connect Clock signal to XTAL IN Pin and Clock to ADAS1000-2 is fed from the clock_io of ADAS1000-4...?
