K15 GPSDO Module

  • Synchronizes to GPS/QZSS, GLONASS, and BeiDou constellations, providing precise time and frequency reference signals for your prototyping and laboratory needs
  • Featuring a U-Blox LEA-M8F GPS receiver specifically designed for time and frequency applications and a TI CDCEL913 PLL to generate 1 PPS, 10MHz sine or CMOS reference clock signals
  • Level-shifters support 3.3V and 5V MikroBUS signals, or coaxial I/O
  • A 5V USB Type-C interface can also power the board and allows U-Blox's U-Center management tool to configure and monitor the LEA-M8F
$149.00
    • Provides timekeeping within 20 nanoseconds (clear sky) and frequency within five parts per billion
    • Concurrent reception of up to two GNSS constellations
    • Accurate measurement and control of external DAC for VCXO
    • Industry-leading acquisition sensitivity and single satellite timing
    • Autonomous 100 ppb hold-over VCTCXO
    • Prepared for integration with external PTP, Sync-E and network listen
    • Integral, disciplined, low phase noise 30.72 MHz system reference oscillator
    • PLL-generated 10MHz reference clock output
      • Absolute Maximum Ratings Min Max Unit
