3. TECHNICAL BRIEF
• MPEG4 video encode/decode
• Video streaming
• MP3 playback
• Java applications.
This single chip solution allows for very small form factor phones with a high degree of power efficiency.
Its low cost structure makes multimedia feature-enhanced EDGE phones very affordable for
price-sensitive market segments. S-GOLDradio
power consumption also makes it the perfect fit for EDGE-capable data cards.
S-GOLDradio 's baseband processing is powered by an ARM926EJ-S CPU and a TEAKLite® DSP core.
TM
The ARM926EJ-S is a powerful standard controller and particularly suited for wireless systems. It is
supported by a wide range of tools and application SW.
The TEAKLite® is an established DSP core for wireless applications with approved firmware for GSM
signalprocessing. The Infineon Technologies DSP firmware and software modules for FR, HR, EFR and
AMR-NB vocoding and channel encoding allow a short time to market. Additionally, S-GOLDradio
supports multislot operation modes:
HSCSD (up to class 10), GPRS for high speed data applications (up to class 12) and EGPRS (up to class
12) without additional external hardware.
A wide choice of communication interfaces allows complex data and multimedia system designs.
Furthermore, S-GOLDradio
optimized forall mobile platform needs (such as graphic displays with backlights) and internal needs
(analog components, loudspeaker, USB, etc.). S-GOLDradio
batteries such as Li-Ion or Li-Polymer batteries. S-GOLDradio
supply voltages by using highly efficient
DCDC converters, DCDC boost converters and linear, low-dropout regulators (LDOs). In addition, it
supports battery charging, generates stand-by voltages and supports different low power modes.
The S-GOLDradio RF capability features a quad-band transceiver for
TM
EGSM/GSM900/GSM1800/GSM1900, and it is designed for voice and data transfer applications. Its
architecture consists of a direct conversion receiver and a quad-band polar transmitter for GSM/EDGE.
Accurate output power setting is ensured by an integrated power control loop, which supports linear and
non-linear power amplifiers. The entirely integrated quad-band RF
oscillator and Sigma-Delta synthesizer give the S-GOLDradio
