IQD adds 5 V atomic clock to its portfolio

IQD Frequency Products introduces the IQRB-4, a 5 V rubidium oscillator The new IQRB-4 bridges the gap between the 12 V powered IQRB-1, IQRB-2 and IQRB-3 and the recently released 3.3 V powered ICPT-1. IQD has been active in the frequency products market for over 45 years and in recent years developed its know-how to specialize in the field of atomic clocks. The company has invested in its design and technical measurement capabilities at its head office in the UK, which also acts as the center of excellence for frequency products within the Wurth Elektronik eiSos Group. This means that customers and interested parties can be offered the maximum possible service that IQD and Wurth eiSos are… Read Full Blog Post

Small Low Height SMD Quartz Crystal

3.2 x 2.5mm hermetically sealed ceramic
4-pad package only 0.8mm high
Automotive version available to AEC-Q200/TS16949 with PPAP levels 1 to 5
Stabilities down to ±10ppm over -40 to +85°C or ±15ppm over -40 to +125°C for automotive applications
Very wide frequency range from 10 to 200MHz
Typical applications: ABS sensors, engine control Units (ECU), ethernet, home automation & entertainment, process management systems, smart lighting, tyre pressure monitoring systems (TPMS) and Wi-Fi

Smallest 32.768kHz clock oscillator

1.6 x 1.2 x 0.7mm hermetically sealed ceramic package
Only 30µA and with a standby current as low as 3µA
Delivers better temperature characteristic than standard 32.768kHz tuning fork crystal based oscillators due to the use of an AT-cut crystal normally found in higher frequency oscillators
Start-up time only 7ms at 3.3V with a rise and fall time of 200ns
CMOS output with supply voltage 1.8V
Typical applications: battery management systems, communication modules and systems (Bluetooth, Wi-Fi, Wireless LAN & Zigbee), LCD lighting systems and smart meters (AMR)

Low Jitter High Frequency VCXO

Excellent low phase jitter performance between 0.05 to 0.3ps RMS max over 12kHz to 20MHz
Very wide frequency range from 1 to 800MHz
Hermetically sealed 7.0 x 5.0mm ceramic 6-pad package
Choice of three outputs: HCMOS, LVPECL and LVDS
Primarily designed for applications such as DSL/ADSL, ethernet (10G/40G/100G), Femto & Pico cells, SONET/SDH and video broadcasting

Ultra Miniature OCXO only 9.7 x 7.5mm

Housed in a 4-pad plastic package with a fibre glass base measuring only 9.7 x 7.5mm
±10ppb stability over -20 to +70°C or ±20ppb over -40 to +85°C
Frequency ageing ‹2ppb per day and maximum of 3ppm over a 10 years
