Description

The W681xxxR-ES has the bare minimum for a digital telephone handset application which will allow the designers to easily connect this small footprint daughter board to their applications. The evaluation system targets developers of such systems as VoIP, Digital Telephony, mobile devices (wireless headsets), PBX that would like to test and or develop with Winbond Family of Voice CODECs into a new system with minimal or no additional analog design at all (“Plug & Play”).

Features

■ Smallest form that contain the bare minimum components to allow a handset/headset application.

■ It allows system developers to bypass the analog in and analog out components with a simplified procedure.

● Prototype area for developer to hook up the side-tone resistor on board or RJ9 (hand-set jack) or headset jack.

● The board has the resistors that will allow the maximum amplification for a 32 Ohm speaker and a standard microphone

● All CODEC pins lead to holes that enable the developer to solder wires to connect to his system board.

● The board is designed to minimize any outside noises for the cleanest signals possible.
