IQD’s latest high performance oscillator, the IQRB-1, offers a stability around a 1000 times more accurate than a typical oven controlled crystal oscillator (OCXO). This means it can be used as a free run frequency source in applications such as LTE (Long Term Evolution) systems that require exceptional timing accuracy. It can also be used for UTMS as well as extended holdover for CDMA and WiMax.

Based around an atomic clock, the IQRB-1 delivers an accuracy of ±5E10-11 irrespective of temperature fluctuations. This compares to IQD highest performance OCXO (IQOV-70 series) which offers a stabilities down to <±3E10-9 (<±3ppb).

This new Sub Miniature Atomic Clock (SMAC) is housed in a 5-pin 51mm square package making it compatible with many existing OCXO footprints whilst offering considerably improved performance. Operating at a standard frequency of 10MHz, the IQRB-1 can accept supply voltages of between 12 and 18 Volts. Power consumption is up to 6W maximum with a warm up time of typically 5 minutes, again making it comparable with many OCXO’s.

The device can be operated over an operating temperature range of -30 to +65°C and Mean Time Between Failure (MTBF) is approximately 100,000 hours. Storage Temperature is rated at -55 to 85 degrees C and it is EMI compliant to FCC Part 15, Class B. Shock and Vibration performance is GR-CORE-63, 4.5.2/4, locked to 1.0G. Standard output compatibility is Sine Wave although HCMOS can be specified if required. The IQRB-1 has 100 times less drift than typical OCXOs and a short term stability of 8E10-11 over a 1 second period.

Pricing is $1142 per unit depending upon quantity required. Further details will be available at the IQD booth 834 at Design West 2013.
