GCT Semiconductor
GCT Semiconductor is a fabless semiconductor company that designs,
develops and markets innovative integrated circuit solutions for the
wireless communications industry. The RF functionality of GCT's products is
based upon its patented direct conversion architecture. This versatile RF
architecture has the ability to support many of the wireless communication
standards, including Bluetooth and IEEE 802.11b/g. The company's long-term
goal is to leverage the multi-mode capabilities of the direct conversion
architecture into semiconductor products that will enable a wireless device
to communicate via several wireless standards.

GDM1000 Radio
Transceiver
GDM1000 is a CMOS RF transceiver with a GFSK modem and frequency-hopping
synthesizer for Bluetooth communications. The GDM1000 incorporates the
complete receive and transmit paths, including PLL, VCO, LNA, PA, mixer,
modulator, demodulator, channel select filters, and digital GFSK modem with
SYNCWORD detector. The GDM1000 chipset requires only an external antenna
and crystal to provide a complete Bluetooth radio. The GDM1000 supports the
standard BlueRF RXMODE2/3 unidirectional and JTAG serial interfaces, which
can connect various kinds of baseband devices.
GDM1101
Single Chip Solution
The GDM1101 is a Bluetooth single-chip CMOS IC with integrated radio
& baseband providing a complete Bluetooth 1.1 solution, which is
comprised of a radio transceiver employing GCT's patented direct conversion
technology, a Bluetooth baseband controller with bit processor, a GCT
proprietary 32-bit embedded RISC processor, and UART/PCM/USB
standard/peripheral interfaces. The on-chip 32-bit embedded RISC processor
is powerful enough to support full rate Bluetooth data communications and
includes sufficient embedded SRAM to support both embedded solutions or
voice applications without external memory, which results in low-power
consumption and a more cost-effective solutions. A few external elements
such as external antenna, crystal and 128KB flash memory are needed for
complete Bluetooth systems.
GDM1201
Baseband Processor
The GDM1201 is one of several Bluetooth ICs offered in the GCT Bluetooth
product family. The GDM1201 is a Bluetooth baseband IC implemented with
CMOS technology. Together with the GDM1000 radio transceiver IC and an
external flash memory, it provides a fully compliant Bluetooth solution for
data and voice communications.
GDM1202
Baseband Processor
GDM1202 consists of programmable seamless Bluetooth RF interfaces such
as BlueQ or BlueRF RXMODE2/3, Bluetooth baseband and bit processor, GCT
proprietary 96MIPS hybrid RISC/DSP embedded processor with 48bit
resolution, and UART/PCM/USB/DAC standard interfaces. The on-chip 32-bit
hybrid RISC/DSP embedded processor is powerful enough to support full rate
Bluetooth data/voice communications as well as full rate digital audio
decoding and includes sufficient embedded SRAM (128Kbytes) to support both
an on-chip Bluetooth stack, A/V protocols and several audio applications
without external memory, thus providing cost-effective and low-power
solution.
Software
GCT will provide the full Bluetooth software stack from the Baseband
layer to the Bluetooth Profiles, including two forms of HCI for hosted
applications- normal HCIimplemented specified in the Bluetooth
specification, and GCT Extended HCI (GXHCI), which has GCT specific
commands abstracted at a higher level.
GCT Bluetooth Development Kit (GBLUE-Kit)
GCT provides a complete development kit for implementing Bluetooth
software and hardware applications along with silicon solutions,which are
also supported by GCT.GBLUE-Kit, GCT Bluetooth Development Kit,is designed
for professional developers targeting both host software and on-chip
applications.
