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, it offers superb phase noise performance with a close in phase noise typically at -110 dBc/Hz @ 1 Hz and a noise floor as low as -158 dBc/Hz. Furthermore, it combines tight tolerance and ±0.3 ppb temperature stability (-20 to 60 °C) with great short term and long term stability. This makes the IQRB-3 the ideal fit for timing applications that require a very precise frequency.
As with all our high-end products, we recognize that measurements given on the datasheet are specific to the test setup and environment, that’s why we have compiled a handbook documenting the precise details for each line on the datasheet. If these don’t match your environment, we are happy to adapt and repeat our measurements as per your requirements.
