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.

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.

(2) Utilizing pins 18 and 19 as USB D+ and D- requires the firmware to Tri-state GPIOs 22 and 23.
(3) Pin 20 (GPIO24) can be utilized to implement a “Data Waiting” interrupt signal for I2C and SPI Slave
data communication.
(4) Pin 21 (RESET_EXT) can be pulled to GND with a switch or an open drain/collector type device to
provide a hard reset signal to the AV5100. This pin is pulled up to VDDIO (3.3V) internally in the
AV5100 and should not be actively driven high.

3 Electrical, Audio and Timing Specifications
Absolute Maximum Ratings
3.1
Absolute Maximum Ratings (AMR) are stress ratings only. AMR corresponds to the maximum value that can be applied without leading to
instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may
cause permanent damage to the device.
Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Range” is
not implied. Exposure to absolute-maximum-rated conditions for extended periods may adversely affect device reliability.
Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test
conditions specified.

3.10 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.

FCC Statement:
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
● Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
