Multi-GNSS Reference Frequency Generator Model: GF-8804/05
Multi-GNSS Reference Frequency Generator Model: GF-8804/05
Achieves frequency stability of atomic clock class. 24-hour holdover performance comparable to rubidium.
The Furuno GF-88 series is a fully functional multi-GNSS reference frequency oscillator (GNSSDO*) that includes a multi-GNSS receiver, a high-precision crystal oscillator (OCXO), an antenna detection circuit, and a low-loss regulator (LDO) all within a compact pin header module. It outputs a 1-second pulse synchronized to Coordinated Universal Time and an accurate frequency. The GF-8805, equipped with a high-precision OCXO, achieves frequency stability equivalent to that of atomic oscillators with a 1PPS accuracy of less than ±1.5μs (over 24 hours), not only during GNSS signal reception but even in a holdover state when signals cannot be received. The GF-8804, which offers excellent cost performance in the same form factor, is also available. By choosing the optimal product from these two options, designers can significantly save time and costs. *GNSSDO: GNSS disciplined oscillator

basic information
【Features】 ■ Outputs a highly stable frequency (10 MHz) and an accurate time pulse (1PPS) synchronized with UTC. ■ Integrates GNSS receiver, crystal oscillator, and peripheral circuits into a single module, reducing the time-to-market for wireless systems (the period from design to market launch). ■ Achieves 5G timing performance in a single band. Compliant with G.8272 PRTC-A and PRTC-B. ■ Ideal for wireless communication and broadcasting. Designed and equipped with features considering various issues that may arise in the market. ■ Offers two models in the "Grande" form factor, pursuing holdover capabilities. ■ The phase relationship between frequency and time pulse is always constant (coherent, jitter-free). ■ Capable of outputting frequency and time pulse with tracking of only one satellite (excluding mobile positioning mode). ■ Synchronization to external pulses. *For more details, please refer to the PDF document or feel free to contact us.
