GPS receiver

The SL871L-S is the companion GPS variant of the SL871L GNSS module. The SL871L-S is designed to comply with both GPS and QZSS constellations and is pin-to-pin compatible with the xL871 Family (SL871L, SL871, SL871-S).

  • Industry standard 10.1 x 9.7 mm footprint
  • Compliant with GPS and QZSS standards
  • Extremely low power consumption
  • Additional DC block for direct input from active antennas
  • Additional LNA for improved sensitivity and faster TTFF
  • A-GPS ephemeris file injection
  • Satellite Based Augmentation System (SBAS)

Product Description

The SL871L-S is the companion GPS variant of the SL871L GNSS module. The SL871L-S includes an ARM7 base band processor, embedded ROM memory and SAW filter. Unlike the standard SL871-S, the SL871L-S embeds also an additional LNA and a DC block. The additional LNA boosts RF sen-sitivity, TFF and the DC block allows direct active antenna input for a seamless integration.

Form Factor Family

The SL871 miniature form factor is a 10.1 x 9.7 mm, 18-pad castellated LCC package ideal for manual and automated manufacturing systems.
