MT6260

GSM/GPRS/EDGE-RX SOC Processor Technical Brief

MediaTek Inc 

Using a highly integrated mixed-signal audio

front-end, the MT6260 architecture provides

easy audio interfacing with direct connection to

the audio transducers. The audio interface

integrates A/D converters for voice band, as well

as high-resolution stereo D/A converters for both

audio and voice band.

MT6260 offers a highly integrated Bluetooth

radio and baseband processor. Only a minimum

of external components are required. MT6260

provides superior sensitivity and class 1 output

power and thus ensures the quality of the

connection with a wide range of Bluetooth

devices.

MT6260 supports AMR codec to adaptively

optimize the quality of speech and audio.

Moreover, HE-AAC codec is implemented to

deliver CD-quality audio at low bit rates.

MT6260 is fully compliant with Bluetooth v3.0

and offers enhanced data rates of up to 3Mbps.

It also provides the coexistence protocol with

802.11 system.

In addition, a 850mW class-AB amplifier is also

embedded to save the BOM cost of adopting

external amplifiers.

GSM/GPRS/EDGE-Rx radio

MT6260 integrates a mixed-signal baseband

front-end in order to provide a well-organized

radio interface with flexibility for efficient

customization. The front-end contains gain and

offset calibration mechanisms and filters with

programmable coefficients for comprehensive

compatibility control on RF modules. MT6260

achieves outstanding MODEM performance by

utilizing a highly dynamic range ADC in the RF

downlink path.

MT6260 supports rich Bluetooth profiles,

enabling diversified applications that are widely

used on the handset with excellent

interoperability.

FM radio

The FM radio subsystem provides a completely

integrated FM Rx receiver supporting 87.5 ~

108MHz FM bands with 50kHz tuning step. It

also performs fast channel seek/scan algorithm

to validate 200 carrier frequencies in 6 seconds.

In addition to receiving FM audio broadcasting,

the digital RDS/RBDS data system is supported

as well. The integrated FM transceiver utilizes

state-of-the-art digital demodulation/modulation

techniques to achieve excellent performance.

MT6260 embeds a high-performance and

completely integrated single-ended SAW-less

RF transceiver for multi-band GSM cellular

system. In this RF transceiver, a quad-band

receiving feature with high sensitivity is

supported utilizing one RF receiver and a fully

integrated channel filter. With ultra-high dynamic

range, the off-chip balun and SAW filters on the

receiving path can be removed for BOM cost

reduction. In addition, the minimum component

count is guaranteed by realizing a highly

integrated transmitter, low-spur frequency

synthesizer and a Digitally-Controlled Crystal

Oscillator (DCXO).

Bluetooth radio

In order to achieve high SINAD, good sensitivity

and excellent noise suppression, the FM

receiver adopts adaptive demodulation scheme

to optimize Rx system performance in all ranges

of signal quality by reference of a very

sophisticated channel quality index (CQI). When

the received signal quality is poor, the design not

only enhances the ACI rejection capability but

also uses a very ingenious skill to soft mute

annoying noise so as to provide good perception

quality.

The FM radio subsystem supports both long

antenna, which is usually an earphone, and

auto-calibrated short antenna, which is usually a

FPC short antenna or shared antenna with GSM

for different application scenarios.
