MT3338V

The MT3338V is engineered for energy efficiency, delivering exceptional GPS performance in a compact, all-in-one chip. It integrates essential components such as an LNA, digital baseband, and ARM7 processor, eliminating the need for external components like antennas, LNA, or image-rejection filters. This chip also features advanced power management, allowing it to operate directly from a lithium battery without requiring external voltage regulators. Furthermore, it includes an embedded RTC (Real-Time Clock) and a battery-backed memory for quick satellite acquisition when the system is restarted.

With an impressive -165 dBm tracking sensitivity and extremely low power consumption (25 mW for acquisition and 18 mW for tracking), the MT3339 excels in both indoor and outdoor environments. It supports multiple satellite systems including GPS, QZSS, and various SBAS systems (WAAS/EGNOS/MSAS/GAGAN).

The chip comes in a small VFBGA package (4.3 x 4.3 mm, 57 balls), integrating everything from CMOS RF to a digital baseband processor and ARM7 CPU. This compact design helps reduce the bill of materials and simplifies integration.

The MT3338V supports a maximum of 66 acquisition channels and 22 tracking channels, capable of acquiring up to 210 PRN channels. It also includes features such as multi-path detection, interference cancellation with 12 multi-tone active cancellers, and RTCM support.
