OPERATIONAL MODES DESCRIPTION
The ISD5008 can operate in many different modes. It’s flexibility allows the user to configure the chip
such that almost any input can mixed with any other input and then be directed to any output. The
variable settings for the ANA and AUX input amplifiers plus the microphone AGC and speaker volume
controls make it possible to use the device with most existing cell phone or cordless phone chip sets
with no external level adjustment. Several modes will be found in most applications, however, please
refer to the ISD5008 block diagram to better understand the following modes. In all cases, we are
assuming that the chip has been powered up with the PU bit in the SPI control register and that a time
period of TPUD has elapsed after that bit was set.
6.5.1
Feed Through Mode
This mode enables the ISD5008 to connect to a base band cell phone or cordless phone chip set
without affecting the audio source or destination. There are two paths involved, the transmit path and
the receive path. The transmit path connects the ISD chip’s microphone source through to the
microphone input on the base band chip set. The receive path connects the base band chip set’s
speaker output through to the speaker driver on the ISD chip. This allows the ISD chip to substitute for
those functions and incidentally gain access to the audio to and from the base band chip set. Figure
15 shows one possible connection to such a chip set.
Figure 16 shows the part of the ISD5008 block diagram that is used in Feed Through Mode. The rest
of the chip will be powered down to conserve power. The bold lines highlight the audio paths. Note
that the Microphone to ANA OUT +/– path is differential
