The RTL8771BW and RTL8771BF are high-performance GNSS single chips that support a multi-standard (GPS/ BeiDou/GLONASS) positioning solution. The RTL8771B(W/F) includes on chip RF, baseband, and RISC CPU. The RTL8771B(W/F) achieves high-performance low-SNR tracking/acquisition sensitivity, and fast Time-to-First-Fix (TTFF). The RTL8771B(W/F) supports up to 210 PRN channels, including 22 simultaneous tracking channels.
The RTL8771B(W/F) also provides various navigation applications including SBAS/DGPS (WAAS, MSAS, EGNOS, GAGAN, etc.) and AGPS, which speed the positioning time. An always-on backed-up memory and a real time clock are provided to accelerate acquisition at system restart up.
Featuring an on-chip integrated LNA, the RTL8771B(W/F) delivers a total receiver noise figure of 2.6 dB (before ADC). The RTL8771B(W/F) has on-chip regulators that are easily integrated into your system without requiring an extra voltage regulator. The crystal support feature allows users to implement low-cost design circuits with minimum BOM cost.
With an embedded 32-bits RISC controller running at 87/43.5MHz, the system performs time-critical processes, including data decoding and positioning. The real-time operating system also allows for efficient task scheduling.
The RTL8771B(W/F) offers an RS-232 data port and I2C interface for data exchange. The configurable RS-232 interface enables use of a higher data rate to send more data, as well as National Marine Electronics Association (NMEA) packets. Standard pre-defined HCI commands make the RTL8771B(W/F) easy and flexible to configure.
A time mark PPS pulse is generated by the RTL8771B(W/F), which is synchronized with GPS time. A General-purpose IO configured as Position-Fixed indicator allows customers to implement system functions. The general-purpose IO with power-on trap functions allows for easier system configuration.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
RTL8771B is an authentic electronic component manufactured by Realtek, categorized under Wireless & RF Integrated Circuits. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official RTL8771B datasheet above.
Electronic component spot-market pricing for RTL8771B fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for RTL8771B depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
