GX500 Operational Description
3.13.1 WLAN
The GX500 supports single-band 2.4GHz IEEE802.11b/g standardization. The WLAN module which is
consisted of the BCM4325 single chip device provides for the highest level of integration for a mobile
or handheld wireless system, with integrated IEEE802.11TM b/g (MAC/baseband/radio). The BCM4325's
integrated CMOS WLAN 2.4GHz power amplifier provide sufficient output power to meet
the need of most WLAN devices. The interface between PMB8877 and WLAN module is the standard
interfaces SDIO v1.2 (4-bit and 1-bit).
3.13.2 Bluetooth
The GX500 provides the Bluetooth 2.0 specification. The Bluetooth module is the optimal solution for
any voice or data application that requires the Bluetooth SIG standard Host Controller Interface (HCI)
using a high-speed UART and PCM. The Bluetooth solution has an integrated radio transceiver that
has been optimized for 2.4GHz Bluetooth wireless systems. It has been designed to provided low
power,low-cost, robust communications for applications operating in the globally available 2.4GHz
unlicensed ISM band. It is fully compliant with the Bluetooth Radio Specification and meets or exceeds
the requirements to provide the highest communication link quality of service
3.13.3 FM Radio
This FM is a function of WYSDNBGX6 module, electronically tuned, FM stereo radio with RDS/RBDS
demodulator and decoder for low voltage applications, with fully integrated IF selectivity and
demodulation. This equipment supports the European Radio Data System (RDS) and the North
American Radio Broadcast Data System (RBDS) modulations. The FM unit supports I2C for
communications, stereo analog output, as well as I2S and PCM interfaces.
