1 Advanced Bluetooth Stereo Solution Silicon Solution Direct conversion CMOS RF Transceiver (GDM1002) Highly integrated SoC for Digital Audio Streaming (GDM1202) System Solution GCT Evaluation Board Kit GCT Core Development Platform PC-based Development Platform GCT Semiconductor, Inc.
2 Advanced Bluetooth Solution for Audio Streaming Applications (GDM1002/1202) Key Features GDM1002 : Highly-Integrated CMOS Direct Conversion Radio Transceiver with BlueRF RXMODE2 Interface Class 2 and 3 (up to 10 meter range) compliant with Bluetooth Specification 1.2 Fully-integrated single-chip transceiver with on-chip PLL, VCO, LNA, up/down converter, and digital GFSK modem Seamless interface to BlueRF RXMODE2 with unidirectional / JTAG serial interface or bidirectional/dbus serial interface Up to - 90dBm receiver sensitivity Superior adjacent channel selectivity of - 6 dbc at 1-MHz offset from the carrier Supports dual reference clock frequency: 13/16MHz 40-pin QFN (6mm x 6mm) package The family of GCT Bluetooth products is comprised of the 2.4GHz radio transceiver and single chip baseband controller for digital audio streaming. GCT provides the full Bluetooth protocol stack with optimized embedded code and profiles, along with a development kit that gives developers maximum flexibility to design, test, and debug software applications for GCT's chipsets. Applications Multimedia USB Dongles, including Standard USB Bluetooth Interface USB Audio (using Audio data compression scheme with SBC Codec) USB storage device functions (GDM1202 features integrated NAND Flash controller) Stereo wireless speaker Portable MP3 players (WMA decoder, MP3 decoder) Portable MP3 CD Players (WMA/MP3 decoder, SBC Codec) VoIP phones (CTP Profile, H.323, ACL link ) Handsfree boxes (echo cancellation) Wireless stereo headset GDM1002 Part of the GCT Bluetooth product family, the GDM1002 is a low-cost, short-range, radio transceiver IC designed for Bluetooth links operating at 2.4 to 2.5GHz. The GDM1002 integrates the complete receive and transmit components including PLL, VCO, LNA, up/down converter, channel select filters, and digital GFSK modem. Based on GCT's proprietary direct conversion radio architecture, the device offers superior channel selectivity and fast automatic gain control. Eliminating the need for external RF board components (such as external SAW filters and balun), the GDM1002 offers a greatly reduced total Bill of Materials (BOM). As a result, it meets the stringent Bluetooth requirement of "smallest form factor", and, since it is implemented in CMOS technology, the GDM1002 provides a low cost alternative for Bluetooth applications.

3 Multimedia SoC for D igital A udio Streaming (GDM1202) Implemented in CMOS technology, the GDM1202 is a single-chip Bluetooth baseband IC with an embedded digital signal processor (DSP). It is designed for use in audio-streaming Bluetooth applications, such as MP3 or WMA digital audio decoders. When combined with the GDM GHz radio transceiver and external flash memory, the GDM1202 provides a fully-compliant Bluetooth radio solution, that is especially suited for digital audio streaming applications. The GDM1202 features a radio interface, a Bluetooth baseband for bit processing, an embedded 32-bit hybrid RISC/DSP, and standard peripheral interfaces. GDM1202 Designed for audio streaming applications, the GDM1202 allows high-quality audio content distribution and supports the Advanced Audio Distribution Profile (AADP) defined in Bluetooth. For a complete Bluetooth solution with minimal BOM configuration, the GDM1202 can be combined with the GDM GHz radio transceiver, an external antenna, crystal, and 256KB of flash memory (for program code). An on-chip embedded processor based on GCT proprietary 128-MHz hybrid RISC/ DSP technology has enough power to handle full-rate Bluetooth data/voice communications as well as computational intensive DSP applications. With 128Kbytes of internal SRAM, the GDM1202 supports both an on-chip Bluetooth stack [including LMP, L2CAP, SDP, AVDTP (A/V Distribution Transport Protocol) and AVCTP (A/V Control Transport Protocol)] and an audio application without additional external memory, thus providing a cost-effective, low-power solution. The GDM1202 uses GCT's optimized C compiler and intrinsic library functions to maximize the software developer's productivity. In addition, GCT provides a performance-optimized DSP library that accommodates several multimedia standards, such as MPEG audio decompression, Dolby Digital decompression, WMA, SBC, and speech codec.
