New Evaluation Board for Standard Oscillators

How many times have you thought that you wished you had a quick and simple way of testing an oscillator? Now there is no need to worry about designing and building your own test circuit as you can use the new IOSC-EV Board available from IQD and our distributors. This can be used to test standard surface mount clock oscillators, VCXOs or TCXO/VCTCXOs. The IOSC-EV Board comes with six smaller boards that can be snapped from the side of the main board and onto which different size 4 pad packaged oscillators can be soldered. The smaller board can then be soldered to the main PCB. The six different package sizes are 1.6 x 1.2mm, 2.0 x 1.6mm, 2.5 x 2.0mm, 3.2 x 2.5mm, 5.0 x 3.2mm & 7.0 x… Read Full Blog Post

Small Low Height SMD Quartz Crystal

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

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 Tight Stability TCXO

Ultra tight stability at ±0.14ppm over -40 to +85°C
Housed in a 7.0 x 5.0mm ceramic package
Phase noise performance of -148dBC/Hz at 10kHz offset and short term stability is down at 5E-10/S
Frequency range 10 to 50MHz
Voltage control options of ±5ppm to ±10ppm or ±10ppm to ±15ppm
