GDM1201

󳢯The GDM1201 is a single-chip baseband controller implemented with CMOS

technology providing Bluetooth functionality for high data rate, short distance

wireless communication in the 2.4GHz ISM band. Together with the GDM1000

radio transceiver IC and external flash memory, it provides a fully compliant

Bluetooth solution for data and voice communications.

󳢯The on-chip 32-bit microcontroller supports the highest data rate in Bluetooth

communications. The architecture of GDM1201 is based on GCT's proprietary

embedded RISC processor for low power processing and includes sufficient

embedded SRAM (64Kbyte) to support the on-chip Bluetooth stack, such as Link

Controller, Link Manager, HCI, L2CAP, RFCOMM and SDP, thus allowing

cost-effective embedded or hosted application solutions.

󳢯GDM1201 supports multiple-standard interfaces, such as BlueRF RXMODE2/3

uni/bi-directional, BlueQ and JTAG serial, which can simplify implementation

with alternate vendors' transceivers, giving the customers outstanding flexibility.

GDM1000

󳢯The GDM1000 Bluetooth single-chip CMOS radio is a highly integrated RF transceiver and modem optimized for use in

2.4GHz Bluetooth communication systems. With on-chip PLL, VCO, and all the other function elements of transmitter

and receiver, the GDM1000 provides averyhigh integration level, thus requiring only an external antenna, antenna switch,

and crystal for a complete Bluetooth v1.1 RF solution.

󳢯This radio IC is based on GCT's patented direct conversion architecture, which offers superior adjacent channel selectivity

and fast automatic gain control and reduces the number of external RF board components such as external SAW filters,

bandpass filters and on-chip inductors, thus meeting stringent requirements of smallest form factor in Bluetooth.

The radio is implemented in a production-ready, high-yield CMOS processes, further enhancing its cost-competitiveness.

󳢯GDM1000 supports the standard BlueRF RXMODE2/3 unidirectional and JTAG serial interfaces, which allow integration

with a variety of different vendors' baseband ICs allowing a high degree of system design flexibility.

bit processing, on-chip 32-bit hybrid RISC/DSP embedded processor,

and standard peripheral interfaces.

GDM1202

󳢯The GDM1202 is focusedon audio streaming applications, allowing high-quality

audio content distribution. GDM1202 supports theAdvanced Audio Distribution

Profile defined in Bluetooth with internal audio DAC. For a complete Bluetooth

solution, the GDM1202 can be integrated with the GDM1000 2.4GHz radio

transceiver, needing only an external antenna, crystal and flash memory.

󳢯The on-chip embedded processor in GDM1202 is based on GCT's proprietary

hybrid RISC/DSP processor and is powerful enough to support both full rate

Bluetooth data/voice communications and computational intensive DSP

applications. With 128Kbytes of internal SRAM, it 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 external memory, thus providing a cost-effective,

low-power solution.

󳢯GDM1202 supports GCT's optimized C compiler and intrinsic library functions

to maximize developer's software development productivity. On top of this,

GCT provides a performance-optimized DSP library for enabling several

multimedia standards, such as MPEG audio decompression, Dolby Digital

decompression, G.723.1/G.728 speech codec, etc.

GDM1101 embedded Bluetooth protocol stack

HOST

GDM1101 is a Bluetooth single-chip CMOS IC with

integrated radio transceiver and baseband controller

providing a complete Bluetooth version 1.1 solution

(excluding external flash memory). GDM1101 consi sts

of a radio transceiver employing GCT's patented

direct conversion technology, baseband controller with bit processor,

GCT's proprietary embedded RISC processor, and standard peripheral

interfaces such as UART/USB/PCM.

GDM1101

󳢯With GCT's patented direct conversion technology minimizing LO coupling

and DC offsets, the GDM1101 surpasses Bluetooth 1.1 performance

requirements, especially for high channel selectivity and broad dynamic range,

thus providing reliable and superior performance in the presence of many

ISM band RF interferers.

󳢯The on-chip 32-bit RISC processor is powerful enough to support full rate

Bluetooth communications. Its instruction set is optimized for bit processing

in embedded solutions or voice applications, which are frequently used in

Bluetooth.

󳢯With 64Kbytes of internal SRAM, the GDM1101 effectively supports on-chip

Bluetooth stack without using any external memory, which results in lower

power consumption and a more cost effective solution for embedded or

hosted Bluetooth applications.
