< 40 mA (peak) • The AGND is connected to the chassis Ground (GND) in the CM52 module, and only there. The application should be connected to GND and only use AGND as reference for the audio lines ATMS and AFMS. - Page 22 Confidential 22(42) USERS MANUAL Document number Revision 4/198 17-LXE 108 566 Uen Application Implementation: BIAS: An analog ground plane should be generated, which connects to GND in one point so that high frequency digital current is not floating through the analog ground. Connecting the analog ground in only one point also avoids ground currents from power supplies and other high current circuitry from creating noise in the analog circuitry.
- Page 23 Confidential 23(42) USERS MANUAL Document number Revision 4/198 17-LXE 108 566 Uen AFMS: An application using the analog audio interface must re-reference the AFMS- signal from AGND to its own internal BIAS. The figure shows a differential implementation. C1 is chosen to create the correct HP frequency response. R1 and R2 determine the gain, and C2 and R2 determine the LP frequency response.
