3.2 Audio Data Capture
AMN11310 transports an explicit audio master clock with appropriate data-over-the-wireless link. No constraints
exist for a coherent video and audio clock, where coherent means that the audio and the video clock must have
been created from the same clock source. The AMN11310 can accept digital audio from either SPDIF or I2S
inputs.
The AMN11310 supports two channel audio sampling frequencies of up to 48KHz and of up to 32 bits per sample
(For I

S Bus Specification
The AMN11310 supports a standardized communication structure inter-IC sound (I
2
S) bus. As shown in Figure 5,
the bus has three lines: continuous serial clock (SCK), word select (WS) and serial data (SD). The external
device generating SCK and WS is the audio source.
Figure 5: I
2
S Simple System Configurations and Basic Interface Timing
The AMN11310 supports an I
2
S format of up to 32 bits for each channel (left and right). The serial data is latched
into the AMN11310 on the leading (LOW to HIGH) edge of the clock signal. The WS is also latched on the
leading edge of the clock signal. The WS line should change one clock period before the first bit of the channel is
transmitted.
The AMN11310 transmits explicit clock SD and WS and does not process the audio content. The input audio at
the transmitter end is mirrored to the receiver end. The source may have different word lengths, up to 32 bits.
However, the AMN11310 always samples and transmits 24 bits over the wireless link.

3.3 Management Buses and Connectors
3.3.1 Two-Wire Serial Bus Interface
The WHDI application observes and controls the AMN11310 via a Two-Wire interface and an interrupt line
connecting the application microcontroller and the AMN11310 MAC microcontroller. The protocol of the Two-Wire
bus for the WHDI application/MAC interface is described in the following sections.
The Two-Wire bus is bidirectional and, as its name implies, has only two wires: a Serial Clock Line (SCL) and a
Serial Data Line (SDA). The Two-Wire architecture includes master and slave devices. The master initiates a
data transfer on the bus and generates the clock signal. The AMN11310 MAC operates as a slave device. Each
slave device is recognized by a unique address and can operate as either a receive-only device or a transmitter
with the ability to both receive and send information.

(Two-Wire Master)
WHDI MAC
(Two-Wire Slave)

SCL
Figure 7: Two-Wire Application/MAC Connection
On top of the Two-Wire low level operation described in sections 3.3.1.3 and 3.3.1.4, the WHDI application and
the MAC microcontrollers communicate with each other in a defined protocol, which avoids all possibilities of
confusion. The protocol defines command oriented transactions between the application and the WHDI MAC.
Each Two-Wire command has a predefined data byte length and is defined to be exactly one Two-Wire
transaction long.
3.3.1.1 Two-Wire Timing
Generally, the clock frequency of the bus is dictated by the slowest device on the Two-Wire interface. However,
the selected MAC supports the 100 KHz SCL frequency rate.
Refer to STM32F Two-wire reference application note for detailed description of the physical protocol and timing.

Each write transaction sends 1 or more data bytes to the MAC, beginning at an explicit 2 bytes long address.
Multiple data bytes may be written as the MAC stores the received register data until the master sends a stop bit.
The MAC updates the register value upon a successful termination of a write transaction.

3.3.1.4 MAC uC Read Operation
This operation reads from a specific 2-byte address. The read transaction is divided into two parts. In the first
part, the Two-Wire master sends a write command to the slave containing only the required start address. (The
address is always 2 bytes long.) In the second part, multiple bytes may be read from consecutive addresses. The
MAC puts the appropriate data on the Two-Wire bus and the internal address is automatically incremented. A
stop bit is sent by the master only when the entire transaction has been completed.

3.3.1.5 WHDI Application/MAC Protocol
The WHDI programmer’s reference defines the MAC registers data structure. Each register has an associated
group ID and index offset address.
The group ID and the index offset are each 1 byte long. Together they define a register address that is 2 bytes
long.
Each register has an attributed length (in byte units). All registers within the same group have the same length.
A Two-Wire transaction to a specific register includes 2 bytes of register address and the register data bytes. The
register is written in one transaction. If the transaction terminates ahead of time or is too long, the MAC issues an
error interrupt and does not store the received values. The register is read in one transaction, as described in
section 3.3.1.4. If the read transaction finishes ahead of time, the MAC issues an error interrupt.
3.3.2 Interrupts
There is one interrupt connected to the WHDI connector. The interrupt source is the AMN2110 MAC uC. For
details about the interrupt, please refer to the Programmer's User Guide. The interrupt active polarity is set in SW
or by configuration resistors on board – see 3.3.3.

3.4 Reset and Wake-up Timer
The AMN11100 has one hard
RESET
input pin connected directly to the AMN2110 and to the STM32F uC, as
described in 3.4. Assertion of the STM32F reset switches the clock of uC to the internal oscillator until the
Albatross does not assert an INIT_DONE interrupt. Assertion of the Albatross reset enables the generation of the
10 MHz clock. After a hard reset, the MAC asserts the SW reset signal which just clears the registers without
resetting the clock generation scheme.
When the INIT_DONE is asserted, it indicates the completion of the Albatross initialization and that the 10 MHz
clock is stable. At that point, the uC switches to the external clock source from the Albatross and enable
communication with the application microcontroller.

Design Guidelines
Version 0.4
AMIMON Confidential 24
6.1.2 General Guidelines
• Keep traces as short as possible.
• Traces should be routed over full solid reference plans.
• Sensitive lines like reset and clocks should be routed with special care.
These lines should be routed over full solid power plans (ground or power).
Traces should be routed at least 2 times the trace width away from other lines in the same routing layer.
Place a series resistor ~30 ohm at the clock source.
• Keep digital signals away from the analog side.
6.1.3 WHDI Lines
• Place series resistors on all output lines (near the outputs pins).
• Series resistors on input lines are unnecessary. (The series resistors should be placed on the interface
board.)
6.1.4 Power and Ground
• Use a solid ground plan.
• Ground plans separation is unnecessary.
• Place decoupling capacitors near power pins. (Refer to the schematics and BOM for recommended values.)
• Analog power pins should be filtered with ferrite beads. (Refer to the schematics and BOM for recommended
values.)
• Add as many ground vias as possible, for better ground connections between layers and better heat
dissipation.
6.2 RF Design Recommendation
6.2.1 RF Components
All passive components must have compatible performance with components used in the Amimon reference
design.
6.2.2 Power Management
The RF power rail 3.3V_RAIL is separated from the digital power rail 3.3 with ferrite bead.
