General descriptions

MT3336 is a high-performance single-chip GPS solution which includes on-chip CMOS RF and digital

baseband. It is able to achieve the industry’s highest level of sensitivity, accuracy and Time-to-FirstFix (TTFF) with the lowest power consumption in a small-footprint lead-free package. Its small

footprint and minimal BOM requirement provide significant reductions in the design, manufacturing

and testing resource required for portable applications.

With built-in LNA to reach total NF to 2.2 dB, you can eliminate antenna requirement and do not need

external LNA. With its on-chip image-rejection mixer, the spec of external SAW filter is alleviated. With

an on-chip automatic center frequency calibration band pass filter, an external filter is not required.

The on-chip power management design allows MT3336 to be easily integrated into your system

without extra voltage regulator. With both linear and a highly efficient switching type regulator

embedded, MT3336 allows direct battery connection and does not need any external LDO, which

gives customers plenty of choices for the application circuit.

Up to 12 multi-tone active interference cancellers (ISSCC2011 award) offer you more flexibility in

system design. The integrated PLL with Voltage Controlled Oscillator (VCO) provides excellent phase

noise performance and fast locking time. A battery backed-up memory and a real-time clock are also

provided to accelerate acquisition at the system restart-up.

MT3336 supports up to 210 PRN channels. With 66 search channels and 22 simultaneous tracking

channels, MT3336 acquires and tracks satellites in the shortest time even at indoor signal levels.

MT3336 supports various location and navigation applications, including autonomous GPS, SBAS

ranging (WAAS, EGNOS, GAGAN, and MSAS), QZSS, DGPS (RTCM) and AGPS.

Through MT3336's excellent low-power consumption characteristic (acquisition 24 mW, track 17 mW),

power sensitive devices, especially portable applications, you will not need to worry about the

operating time anymore and can have more fun. Combined with many advanced features including

AlwaysLocate

TM

, HotStill

TM

, and EPOTM function, MT3336 provides always-on position with minimal

average power consumption. The great features provide you supreme experiences for portable

applications such as DSC, cellular phone, PMP and gaming devices.
