S Q How do I control the APM PGA gains on BCM1103 BCM1104 A Instructions on how to control the APM gains are in the Appendix C Defining Platform Specific Audio Configuration section of the PhonexChange Endpoint Module Technical Reference Manual SIDETONE DELAY Q What is the sidetone delay A For the BCM1101 BCM1100 sidetone is generated in the DSP software so the delay includes the media queue buffering time in the DSP software A 2 5 ms delay is introduced during ingress sampling and an additional 2 5 ms delay is introduced during egress sampling The total sidetone delay is therefore 5 ms For the BCM1103 BCM1104 BCM1190 the sidetone is implemented in hardware inside the APM block The estimated sidetone delay is in the order of 10 s of usec The sidetone delay is mainly introduced from the Y filter of the APM where the sidetone is generated at 100 kHz sampling frequency A negligible delay is also introduced from the rest of the sidetone pathway through the CIC filter and the analog path The block diagram of the APM path is shown in the APM Block Diagram of the applicable data sheet E Broadcom Corporation Document 110X_111X_119X FAQ104 R Endpoint Page 23 BCM110X BCM111X BCM119X Frequently Asked Questions 10 15 08 APM LOOPBACKS ON THE BCM1103 1104 AND 1190 Q How can Ido APM loopback on the 1103 or 1104 A There are two different APM loopbacks that can be performed e Loopback from the ADC to the DAC
