Product Description The SL871K2L series is part of the SL871 module family. It is based on the low-power AG3352 platform from Airoha. This module series share the same pinout and form factor of the industry established xL871 products. This multi-constellation receiver supports all global constellations (GPS / GALILEO / BEIDOU / GLONASS), in addition to the regional QZSS signal. The SL871K2L module tracks allconstellations in the L1 frequency by default, including the modern Beidou B1C signal. This product outputs a precise one pulse per second(IPPS). Furthermore, it embeds timing-related features like time receiver autonomous integrity monitoring (TRAIM) and surveying mode for high-performance timing applications.* The SL871K2LsupportsassistedGNSS(A-GNSS) in autonomous and server-based modes. • GPS, GLONASS, Galileo, BeiDou, QZSS, satellite-based augmentation systems (SBAS) • 1PPS with precise timing capabilities (8 ns jitter*) • Timing features (TRAIM, satellite hold, self-survey mode)* • Low-noise amplifier (LNA) and post-amplification filter • Multiple low-power options • Adjustable update rate 1-10 Hz • Adjustable timepulse output rate • Multiconstellation support for better performance and multiple timing information sources • Accurate timing capabilities* • Hardware variants for optimized cost and consumption • Footprint compatible with SL871 series in 9.7 x 10.1 mm industry standard Family Concept The SL871 form factor allows customers to choose from different GNSS technologies using a similar footprint. Modules in this family are offered in a 9.7 x 10.1 mm LCC package. Our positioning product portfolio results from over 30 years of experience in GNSS applications. Typical applications include: • Fleet management systems • GPS- and GNSS-assisted road tolling • Cellular base stations • In-car navigation • Asset tracking • Personal sports training monitors
