Multi-GNSS Disciplined Oscillator Model GF-8801/02/03
Ultra-small size form factor featuring atomic clock level frequency stability with 24h holdover.
GF-88 series is a full-featured multi-GNSS disciplined oscillator (GNSSDO), embedded with multi-GNSS receiver, OCXO, LDO regulator and antenna detection circuit in a compact pin-header module.
It provides outputs of one-second pulse (1PPS), synchronized with Coordinated Universal Time (UTC), and reference frequency (10MHz) signal.
Combined with ultra-miniature OCXO, GF-8802 / 8803 (approx. 34mm x 27mm) builds up a holdover function which can maintain within 10μs / 24 hours(ex.GF-8803) in case that GNSS falls into unlock. There is also low-profile module called GF-8801 embedded with TCXO on the same form factor. 3 available models save significant time and effort during product design.
