1 Document Scope
This document describes interface requirements for the second-generation Play-Fi Wireless Module, also
known as Caprica2L. Caprica2L is a WiFi audio module designed for wireless, multi-room audio
distribution. Caprica2L streams with 16 bit resolution and 44.1 KHz sampling rate. The module may be
utilized in speakers, stand-alone receivers or incorporated into other products like AVRs. This document
provides guidelines for the inclusion of this module into such products.

4 Features
BT Disable
The Caprica2L Play-Fi Wireless module is a programmable, high-performance, encapsulated design
that enables manufacturers to wirelessly distribute audio to multiple devices. Sources can include PlayFi Applications, Play-Fi Drivers, or other sources of a manufacturer's choice, such as Bluetooth, via a
I2S input. The design supports a number of interfaces that enable easy integration of the module to
traditional consumer electronic designs. Caprica2L features include:
4.1 800MHz ARM-based Processor
Marvell PXA166 ARM v6/v7-compatible core:
 Up to 1848 DMIPS
 16K/16K L1 I/D Caches
 64K L2 Cache
 5-8 Stage Variable Pipeline
 Retire up to 2 Instructions per Cycle
 Out-of-Order Execution
 Three-level Branch Prediction
4.2 wMMX2 DSP Support
Up to 1600 MMACS per second. Supports complex Digital Signal Processing with little CPU overhead.
Audio CODECs including MP3, WMA and AAC utilize the wMMX2 engine.
4.3 802.11a/b/g/n 1x1 Wi-Fi
Dual-band design with 2.4GHz and 5GHz support. Supports transmit modes up to 150mbps.
4.3.1 20MHz and 40MHz Channels
Supported in both 2.4 and 5 GHz bands
4.3.2 Diversity Antenna Support
Caprica2L supports two antenna connections in a diversity antenna configuration (using
orthogonal mounting).
4.4 128MB DDR3 Memory
High-performance memory for maximum processor and network performance.
4.5 128MB SLC Flash Memory
4.6 I2C
The I2C Interface is the port which Caprica2L communicates with the external system. The
communication protocol "Play-Fi Host Communication Protocol" is described in a separate document
(PHORUS-CAP- TSD-0004-Caprica-Host-Communication-Protocol). The Caprica2L Module is configured
as a I2C slave with address 0x52.

4.7 I2S Output
Caprica2L outputs digital audio via an I2S port. Caprica acts as the master device. The format is
MSB Left Justified.
LRCLK- 44.1 KHz
BITCLK- 2.8224 MHz (64 * Fs)
Data – 16 bits of data followed by 16 bits forced 0 on each rising/falling edge of LRCLK
This format cannot be changed.
4.8 I2S Input
Caprica2L can accept auxiliary inputs via I2S. Caprica is the slave here. The format is MSB Left Justified.
LRCLK- 8KHz, 16KHz, 22.05KHz, 32KHz, 44.1KHz, 48KHz, 96Khz. (PIN 67)
BITCLK- 2.8224 MHz (64 * Fs) (PIN 65)
Data – 16 bits of data followed by 16 bits forced 0 on each rising/falling edge of LRCLK
This format cannot be changed. (PIN 69)
4.9 USB 2.0HS OTG
Configured as a Host in standard configurations. All Play-Fi devices require a USB Host is required for Factory
USB updates.
4.10 Wi-Fi LED Control
Caprica2L controls a consumer-facing LED that gives indication as to Wi-Fi status.
5 Radio Frequency Performance
5.1 RF Interface
Wi-Fi RF connectivity is provided by 2 dual-band antennas, connected via miniature RF cables. These
antennas are tuned for both 2.4GHz and 5GHz operation.
5.2 Antenna Placement
For optimal RF coverage, antennas should be mounted orthogonally to each other. Each antenna should
be at least 35mm away from any other metal object in 3D space. The antennas should be mounted as
high on the vertical axis as possible while maintaining 35mm distance from other metal objects. The
farther apart the antennas are mounted from each other the better, however, the feed line from antenna to
Wi-Fi Module connection should not exceed 150mm to minimize RF losses through wire.

6.3 Interface Connector Information, Mechanical
6.3.1 80-pin Board-to-Board Connector
The Caprica2L utilizes a 0.5mm BTB SMT Female type, P/N: 8396-8041 (See 880790800A1_88079-xxxxAx-aces_rev-U.pdf) for Board to Board (BTB) connection.
6.3.2 Wired Ethernet Connectivity
The Caprica2L has the capability to be connected to a network via Ethernet cable. To implement
this functionality, USB to Ethernet part ASIX AX88772C and a USB HUB device are required. USB
HUB Device should be a 4-port device. Use port configuration shown in image below.

6.3.3 Apple Authentication Coprocessor Integration
Caprica2L supports integration of Apple Authentication Coprocessor. This is required for builds which wish to
certify Apple AirPlay. The interface between Caprica2L and Apple Coprocessor requires three connections, 2
connections for I2C and one for Reset. The Caprica2L pins designated for this are pin 46 (SCL1), pin 48 (SDA1),
and pin 66 (GPIO1) for reset. The GPIO1 connection is a jumper while SCL1 and SDA1 require external pullup
resistors. Apple MFi Accessory Interface Specification recommends using 2.2k Ohm resistors for pullup to Vcc
used to power Coprocessor.

FCC Warning
Information to user
Any changes or modifications not expressly approved by the party responsible for
compliance could void your authority to operate the equipment.
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 or more 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.
Labelling requirements
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, including interference that may cause undesired
operation.
RF Radiation Exposure Statement:
1. This Transmitter must not be co­located or operating in conjunction with any other
antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a
minimum distance of 20 centimeters between the radiator and your
body.
IC Warning
This device complies with Industry Canada license‐exempt RSS standard(s). Operation
is subject to the following two conditions: (1) this device may not cause interference,
and (2) this device must accept any interference, including interference that may
cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux
appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions
suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de
l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.

OEM Statement:
Labelling Requirements for the Host device
The host device shall be properly labelled to identify the modules within the host
device. The certification label of the module shall be clearly visible at all times when
installed in the host device, otherwise the host device must be labelled to display the
FCC ID and IC of the module, preceded by the words "Contains transmitter module",
or the word "Contains", or similar wording expressing the same meaning, as follows:
Contains FCC ID: 2AAWQ‐CAPRICA2L
Contains IC: 11138A‐CAPRICA2L
This module is intended for OEM integrator. The OEM integrator is still responsible
for the FCC compliance requirement of the end product which integrates this
module.
20cm minimum distance has to be able to be maintained between the antenna and
the users for the host this module is integrated into. Under such configuration, the
FCC radiation exposure limits set forth for an population/uncontrolled environment
can be satisfied.
