GNSS Disciplined Oscillator Board

The VIAVI Mini-JLT Board is a compact GNSS-disciplined oscillator board designed as a form-fit-function replacement for legacy Trimble Mini-T™ GPSDO units. It delivers high-precision frequency and timing synchronization with concurrent multi-GNSS tracking, making it ideal for telecommunications, defense, industrial, and embedded applications.

Features:

• Form-fit-function replacement for Trimble Mini-T™ GPSDO
• 72-channel concurrent GNSS receiver
• Tracks GPS, Galileo, GLONASS, BeiDou, QZSS, and SBAS
• USB and TTL serial communication
• Additional 10 MHz +13 dBm output
• External 1PPS input and integrated 3-axis accelerometer
• Extended operating temperature (-40°C to +80°C)
• Improved thermal stability, phase noise, and Allan Deviation
