Description
The CDB6420 allows an end-user to quickly and easily
integrate the CS6420 Full-Duplex Speakerphone IC into
a system and evaluate its performance.
comes with software which allows the registers of the
CS6420 to be manipulated from a personal computer
running Windows. Evaluation requires a +5 V power
supply. Connections for analog audio sources are pro-
vided on the board.
The CDB6420 includes a business card-sized section
which contains the CS6420 and all the elements neces-
sary to provide a speakerphone interface. This section
is available for direct insertion into a target system, if the
target system can provide the signals required by the
