It generates from it a 3.3V/1.2A supply and a 1.8V/0.8A used by the carrier board and the Galileo module. 1.3.1 Regulator 3.3V From 5V, generate 3,3V power supply used by the Galileo module and the level-shifter.
1.3.2 Regulator 1.8V From 3.3V, generate 1.8V power supply used by the Galileo module, the slow clock and the level-shifter. 1.4 Level shifter The level shifter is used to change the 1.8V signals coming from the Galileo module to a 3.3V signals compliant with the MLB signal requirements, and vice-versa.
The signals converted from 3.3V to 1.8V and 1.8V to 3.3V are as followed: • WIFI_PWR • WLAN_IRQ • BT_PWR • BT_RX • BT_TX • BT_RTS • BT_CTS Notes: (1) The CPU on the MLB is configured to work with 1.8V signals. In this case the SDIO signals out of the Galileo module do not need to be modified. (2) Provision is made to convert the CLK_32kHz and all SDIO signals via the level shifter through uncounted resistors. 1.5 Clock 1.5.1 32kHz Slow clock for the Galileo module 1.5.2 26MHz Internal fast clock of the Galileo module This document is intended for Intermec Development Engineering and System Test Engineering.

2 RC12 Overview RRRRC12 C12 C12 C12 is an embedded wireless device platform that uses a 90 PAD Land Grid Array (LGA) form factor to allow for a low cost solution to mount highly integrated chipsets or OEM/ODM MODULESMODULESMODULESMODULES onto Intermec products. Galileo uses solder-down re-flow mounting only to a host MLB – there are no screws, digital or RF connectors. Test jigs are required to operate Galileo outside of a product. Figure Figure Figure Figure 1111: RC12 platform: RC12 platform: RC12 platform: RC12 platform The RC12The RC12The RC12The RC12 is an Intermec designed radio platform incorporating the MuRata WLAN/Bluetooth radio module LBEH1Z9PFC-TEMP. Please see reference section for data sheet. This device is a dual function IEEE 802.11 bgn transceiver, a Bluetooth 2.1 compliant radio transceiver. The module contains independent transceivers for each radio technology; IEEE 802.11 and Bluetooth. This variants system is capable of operating at the 2.4 GHz for the IEEE 802.11 transceiver, or 2.4 GHz band for the Bluetooth transceiver. The MuRata MODULE is based on the following 802.11 and Bluetooth chipsets from Texas Instruments; WL1273 Single-Chip MAC baseband processor and RF transceiver supporting 802.11 b/g/n standard The RC12The RC12The RC12The RC12 and subsequent variants will be manufactured by Contract manufacturer. Intermec is responsible for ensuring proper manufacturing test of the current and future designs. 2.1 IEEE802.11 transceiver description The IEEE 802.11 transceiver is based on the Texas Instruments WL1273 single-chip IEEE 802.11bgn MAC, Baseband, and Direct Conversion transceiver. This system functions to provide wireless LAN connectivity supporting data rates from 1 Mbps to 54 Mbps and MCS0 to MCS7 in the 2.4-GHz band. The Triquint TQP6M9002 provides RF frontend capabilities for the 2.4 GHz. This variant only allows the 2.4 GHz transceiver to be in operation. The Texas Instruments WL1273 employs a 4-Wire SDIO system bus interface to the HOST. The PLATFORM uses a single antenna port for the 2.4 GHz of the IEEE transceivers. The system provides a typical power output in the 2.4 GHz band of 17.5 dBm. The 2.4 GHz transceiver supports data rates of 1, 2, 5.5 and 11 Mbps using CCK/DSSS and 6, 9, 12, 18, 24, 36, 48 and 54 Mbps using OFDM as per IEEE802.11-2007. Data rates MCS0 to MCS7 conform to amendment IEEE802.11n-2009.
The system is designed to only use the 20 MHz occupied BW capacity. Data rates MCS0 to MCS7 conform to amendment IEEE802.11n-2009. Data transmission from the IEEE transceiver is initiated by the IEEE 802.11 compliant MAC software. The source of data to transmit can either be user supplied data (from the host systems) or network control packets (ACK’s CTS, PSPoll, ProbeRequest etc). The transmitter is only active during the transmission of one of the packets previously mentioned. 2.2 Bluetooth transceiver description The Bluetooth subsystem is built on the Texas Instruments BRF6450 ; a single-chip CMOS, Bluetooth® 2.1-compliant, Enhanced Data Rate (EDR) capable, stand-alone baseband processor with an integrated 2.4-GHz transceiver. The BRF6450 transceiver uses the Bluetooth SIG standard Host Controller Interface (HCI) via 4-Wire HighSpeed UART and PCM audio interfaces. The BRF6450 incorporates all Bluetooth 2.1 features including eSCO, AFH, and support for collaborative coexistence with WLAN devices. The Bluetooth transceiver uses a single independent antenna that is common with the IEEE Transceiver. The Bluetooth transceiver is built with a Bluetooth Class 1.5 specification RF output power (approx +6 dBm, for an approx 50meter range). The Bluetooth transceiver uses Bluetooth compliant frequency hopping spread spectrum to cover 79 channels 1 MHz wide from 2.402 GHz to 2.481 GHz. The Bluetooth transceiver supports Bluetooth Basic data rates of 1 Mbps (GFSK) as well as Enhanced Data Rates of 2 Mbps (π/4-DQPSK) and 3 Mbps (8-DPSK) Data transmission from the Bluetooth transceiver is controlled by software in the baseband processor. 2.3 Simultaneous operation Simultaneous operation of the WL1273 and BRF6450 transmitters is not possible when WiFi is operating on 802.11bgn (2.4 GHz). While in operation, coexistence is always enabled. This arbitrates packets so that WiFi and Bluetooth packets are alternately transmitted. That is the transmissions are time division multiplexed. The test tool does not allow simultaneous transmitter operation of 802.11bgn or 802.11an and Bluetooth.
