Novus offers a range of GNSS GPS disciplined oscillators and related reference products. While our most popular frequency reference is 10MHz, many of our products are available at 50 and 100 MHz. Unique frequencies are available as well. Novus references can be OCXO , TCXO or Rubidium based. GNSS-locking enhances long-term stability. Stability options are available that incorporate vibration and thermal isolation. Our reference products are available in 19 inch rack mount and modular, chassis. Our miniature PicoPod series fits almost anywhere. Novus reference distribution amplifiers offer minimal phase noise contribution and skewing. Novus PPS sources can be synchronized to a 10 MHz reference to provide a complete timing solution. Our PPS sources can be directly from a GPS PPS source or processed to improve jitter and statistical accuracy. For GNSS denied environments, Novus offers a range synthesized 1PPS sources. Our PPS distribution amplifiers offer sub 1 nsec skewing and transient and fault protection. For enhanced control and monitoring, SNMP and local control are available as options. Portable reference products offer excellent holdover stability to provide accuracy in GNSS denied environments.
The NR3620-LT is a source of NMEA and PPS when a 10MHz reference is not required. PPS pulse 15ns accuracy at 1 sigma. PPS capable of driving a 50 ohm load. A good choice for general lab use, Simulcast and test systems.
• GNSS lock indicator and built in self test.
• Operates from DC Power in three ranges +- (10 to 18, 18 to 36, 36 to 65) Vdc or an AC adapter.
• PPS Accuracy 15 ns @ 1 sigma
• Indicators and signals provide GPS lock and unit self-test status.
• Available in GPSDO kit form (Includes reference, active antenna, 50′ cable, and power adapter).
• PPS pulse width programmable in 1 ms steps to 0.5 sec
• PPS amplitude 3.3 or 5 Vdc CMOS with 50 Ohm load capability.
GPS DO Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
