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. 2 Definitions 2.
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.
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.

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.
