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.

The board

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

CS6420 Network Interface.
