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, howev-
er. Please refer to the ISD5008 block diagram to
better understand the following modes. In all cas-
es, we are assuming that the chip has been pow-
ered up with the PU bit in the SPI control register
and that a time period of T
PUD
has elapsed after
that bit was set:
5.1
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. Fig-
ure 15 shows one possible connection to such a
chip set.
FEED THROUGH MODE
Figure 16 shows the part of the ISD5008 block dia-
gram 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.
