Description and Features
The 5186GB is a very low-cost, low power consumption and industry’s mostly integrated simultaneous dual-channel GNSS receiver covering both GPS L1 and Beidou B1 or Glonass G1 bands on a single-chip. With proprietary integration technology, external component count is kept at minimum. The integrated fractional-N frequency synthesizer allows programming of IF frequency within ±10Hz accuracy. The integrated ADC outputs provide data for the GNSS core signal processing within the baseband and is programmed between 2-bit and 4-bit. 5186GB is a package of 4mmX4mm 24-pin QFN.
