Input
Analog Power. The MSM6679AL-110's on-chip A/D converter uses this
analog power when converting an analog signal into digital samples. Also
this is used as an analog reference voltage.
input. Signal conditioning, via a bandpass fillter and gain circuit, is required
before this input.
independent grounding of the analog and digital circuitry. Separate grounds
reduce the impact of digital switching noise on analog sampling accuracy.
Serial Port Receive. This is the receive data line for serial port.
Serial Port Transmit. This is the transmit data line for serial port.
