Low noise rubidium oscillator with 1 PPS input/output

IQD Frequency Products, a subsidiary of the Würth Elektronik eiSos Group, is currently focusing its engineering expertise on providing best-in-class rubidium atomic clock oscillators. Following the recent releases of new products in this portfolio, the ICPT-1 and the IQRB-4, and an extensive update on the IQRB-1, IQD is now able to share new data on the IQRB-3.

The IQRB-3 can be synchronised to a 1 PPS signal as well as used as a 1 PPS source. Additionally, the company say, it offers “superb phase noise performance with a close in phase noise” typically at -110 dBc/Hz at 1 Hz and a noise floor down to -158 dBc/Hz. Furthermore, it combines tight tolerance and ±0.3 ppb temperature stability (-20 to 60 degrees C) and the company says it offers good short-term and long-term stability. This suits the IQRB-3 to timing applications that require a precise frequency.

Measurements given on the datasheet are specific to the test setup and environment, but IQD has compiled a handbook documenting the precise details for each line on the datasheet. The company says that if these do not match customer environment, it is able to adapt and repeat measurements as per requirements.

The new IQRB-3 handbook is available from the IQD sales office.
