Note:  When only four electrodes are required in the application, it is recommend to use RX channels RX1…RX4,

while RX0 can be left disconnected.

6.5

Analog-to-Digital Converter (ADC)

As outlined in the previous section, each Rx channel features a dedicated ADC with a trigger derived from the

internal clock. ADC samples are synchronous with twice the Tx transmit frequency.

6.6

Signal Processing Unit (SPU)

The MXG3141 features a Signal Processing Unit (SPU) to control the hardware blocks and process the advanced

DSP algorithms included in the GestIC Library. It provides filtered sensor data and recognized gestures to the

application host. The host combines the information and controls its application.

6.7

Parameters Storage

The MXG3141 provides an embedded 128 kB Flash memory which is dedicated to the GestIC Library and storage of

the individual configuration parameters. These parameters have to be set according to the individual electrode design

and application.
