1 Functional Description

The SWA51 module is available in 2 variations; digital input transmitter module or digital output receiver

module.

There are three available I2S digital audio data inputs/outputs, each of these can be configured to operate as

either a master or a slave - depending on the application, the I2S ports can operate simultaneously as either

inputs or outputs. When configured as slaves, the I2S inputs/outputs can be independently clocked by up to

two external masters. In addition, MCLK can be output from the module to provide a reference clock source to

an external ADC or DAC. MCLK can also be input to the module to provide a reference clock from an

external source.

The hardware for the audio input (transmit) and audio output (receive) versions of the module is identical and

only the firmware loaded onto the module determines its function.

The highly integrated nature of the AV5100 transceiver IC results in few external components being required

for the SWA51 module design. 2 printed PCB antennas are used to achieve increased range, and to achieve

antenna spatial diversity. The extended-range RF path consists of the antennas, associated tuning

components, shield can, the RF switch, and two baluns, one connected to each of the RF input/output ports

on the AV5100 IC.

A 16MHz crystal oscillator generates the AV5100 fundamental system clock used as the basis for all RF and

digital audio clocks.

A 2Mb flash memory chip is used to store the module’s application firmware. The AV5100 is able to boot from

internal ROM upon first power up, which enables programming the flash chip with the application firmware . In

addition, Over-the-air Firmware upgrade capability can be enabled through the application firmware. The

module can be controlled from an external host device via the I2C Slave or the SPI Slave data interfaces. The

I2C master port allows the module to control other system audio devices such as a sub-woofer amplifier

system without having to add another MCU to the product design. Up to 9 additional GPIOs are available on

the SWA51 module (not including I2C and I2S signals) for implementing different UI features on the target

application. The resources mentioned above can be leveraged to implement low cost sub-woofer designs as

outlined below.

1.1 SWA51 Module Connections and Interfaces

Signal Type Description

+3.3V Supply The SWA51 hardware is configured to accept a nominal +3.3V supply.

Reset Active low reset input. This pin is driven from an open collector/drain device such

that it can be pulled to ground for the active reset state but, when released, must

go to a high impedance state. This pin should not be actively driven high, as the

AV5100 internal reset circuit will not operate correctly.

I2S In Port The I2S input port can be configured as a master or slave. Consequently BCLK

and LRCK can be either inputs or outputs. In addition, MCLK can be sourced by

the module on pin 16. Since the AV5100 IC contains a sample rate converter,

MCLK is not required to be supplied to the module when it is an I2S slave.

CMOS 3.3V logic levels are used for all I2S signals.

I2S Out Port The I2S output port can be configured as a master or slave. Consequently BCLK

and LRCK can be either inputs or outputs. In addition, MCLK can be sourced by

the module on pin 16. Since the AV5100 IC contains a sample rate converter,

MCLK is not required to be supplied to the module when it is an I2S slave.

CMOS 3.3V logic levels are used for all I2S signals.

I2C Slave Port The I2C slave port can be used for external host communication and for module

testing. It is assumed that external pull up resistors are connected at the I2C

master communicating with the module.

I2C Master Port The I2C master port is used to communicate with external audio devices such as

a sub-woofer amplifier. It is assumed that external pull up resistors are included

on the application board.

GPIOs 3.3V CMOS logic level GPIOs available to connect to other devices, or to use as

UI supporting GPIOs for LED and button support. All supported GPIOs can be

configured as outputs or inputs with configurable pull-ups/pull-downs.

I2C Master/Slave Communication Interface Timing (S_SCL, S_SDA)

The SWA51 has both I2C slave and master interfaces available with their respective pins S_SCL, S_SDA and

M_SCL, M_SDA. The interfaces operate in I2C fast-mode and can receive and transmit at up to 400 kbit/s.

Bytes are 8 bits long and are transferred with the most significant bit (MSB) first. Each byte has to be followed

by an acknowledge bit. The SWA51 will apply clock-stopping (by holding the clock line S_SCL LOW to force

the master into a wait state) if necessary due to internal high-priority tasks.

The slave/master interface can be used both for writing (e.g. sending commands) or reading (e.g. requesting

status). An additional GPIO pin on the SWA51 (Ex. GPIO24), can be used to notify the I2C master when a

pending message is ready to be sent.

The SWA51 slave interface responds to the 7-bit slave address 1000000 (0x40) as shown in Figure 1 below.
