AMBE-3000F™ Vocoder Chip Users Manual
Version 3.4, April, 2014

5.1 Operating Modes Introduction
There are two modes (codec mode and packet mode) for the AMBE-3000F™ vocoder chip. Both modes can take advantage of
the variety of interfaces available.
A good technique for smooth operation and data transfer is to design the system so that the AMBE-3000™ Vocoder Chip boots
into Packet Mode on start-up. This will allow the AMBE-3000™ Vocoder Chip to be sitting idle and ready to receive
configuration packets, independent of the channel interface being used. The user can then configure the AMBE-3000
Vocoder Chip as needed. This method is beneficial because it puts the chip in a known state until it is ready to be utilized.
Figure 19 Switching between Packet and Codec Modes shows a flow chart of the events need
ed to switch between the two
modes.
