System Overview
The MX5000A Development System allows manufacturers to easily evaluate and prototype
system improvements by adding MaxxAudio psycho-acoustic processing to existing audio
systems. The MX5000A Development System contains the small MX5000A Prototype
Module as shown in Figure 1, with simple connections for analog stereo input and output.
The MX5000A Development System also includes a Telos USB to I2C emulator with a
sophisticated PC graphic user interface. It also can be used without any external controls by
using the on-board potentiometers as audio controls.

Controls
The MX5000 Prototyping Module supports two different control options.
a) I2C Slave Mode
b) I2C Host Mode

I2C Slave Mode Controls
In addition to the MX5000 Prototyping Module, the MX5000A Development System is
MM or Connii which enables connection to the USB port of a Windows XP PC along with
associated software. A special cable is also provided to connect between the Telos emulator
and the 4pin I2C header on the MX5000A Prototyping Module. These three items are shown
in Figure 4.

Digital Audio Input/Ouput
For digital audio I/O, the system supports three stereo inputs and two stereo outputs as
shown in Table 1. All inputs and outputs are synchronous with shared clock and synch pins.
The digital audio input/output is supported only in I2C Slave Mode of the MX5000A.

I2C Host Mode Controls
In I2C Host Mode, the MX5000 will read audio parameters from the external serial flash ROM
after reset. After reset, the system will continuously monitor the value of external analog
control pins for real-time audio controls. These pins are connected to eight potentiometers
on the MX5000 Prototyping Module for OEM presets and user controls, which are
summarized in Table 2.
The MX5000 will support most of its major functions in I2C Host mode. Some functions, like
MaxxEQ, require modifying the flash ROM for static customized parameters, or can be used
fully dynamically (and clicklessly) in I2C Slave Mode.
