This trend is partly driven by IC manufacturers, who often design one chipset suitable for both industrial and automotive applications, and by the increased use of electronic devices in more extreme environments. Additionally, the internal self-heating of electronic components close to the crystal on the board can be a motivation to select a crystal that is guaranteed to operate within the specification up to 125&amp;#176;C. Customers who are using the same frequencies in multiple projects with different temperature requirements, may also benefit from selecting one extended temperature part that is designed to work within all these applications rather than having to source and stock multiple parts. IQD&amp;#39;s range includes crystals housed in the popular 4-pad SMD ceramic packages 2.0 x 1.6 mm IQXC-42 with the extended operating temperature range of -40 to 125&amp;#176;C. IQXC-42 is available in frequencies from 16.0 MHz to 72 MHz, with various load capacitances. The parts are offered with ESR values are specified slightly lower than for the existing range of crystals in order to meet the demands of new microcontrollers, which often require lower ESR, for example for IoT applications. These parts are recommended for multiple applications, including Internet of Things (IoT and IIoT), e.g.: Ethernet Green and smart energy applications (Solar inverters) Industrial Control Systems RFID Test and Measurement Systems Telemetry systems Transportation systems WiFi modules Find IQXC-42 on Farnell here .</description><category domain="https://community.element14.com/products/manufacturers/iqd-frequency-products/tags/crystal">crystal</category><category domain="https://community.element14.com/products/manufacturers/iqd-frequency-products/tags/timing">timing</category><category domain="https://community.element14.com/products/manufacturers/iqd-frequency-products/tags/quartz">quartz</category><category domain="https://community.element14.com/products/manufacturers/iqd-frequency-products/tags/frequency">frequency</category></item><item><title>IQD announce return to ITSF 2024</title><link>https://community.element14.com/products/manufacturers/iqd-frequency-products/c/e/1718</link><pubDate>Mon, 04 Nov 2024 12:30:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:a381b09e-05a1-435f-9eeb-96cb9fed4795</guid><dc:creator>IQD-Frequency</dc:creator><description>IQD is delighted to announce a return to the ITSF 2024 again this November where we are Tutorial Sponsors.

It could be a handy general-purpose project for checking phase noise of any 10 MHz source (although it still needs a lower-phase-noise reference).</description></item><item><title /><link>https://community.element14.com/products/manufacturers/iqd-frequency-products/b/blog/posts/disciplined-oscillator-offers-extended-holdover?CommentId=7dc348c9-afb3-4a03-a16f-b15029c4e9f4</link><pubDate>Mon, 23 Sep 2024 18:03:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:7dc348c9-afb3-4a03-a16f-b15029c4e9f4</guid><dc:creator>shabaz</dc:creator><description>It&amp;#39;s a massive challege, the specs are impressive. Just speculating, maybe there are some ways a theoretical review/RoadTest could be done &amp;quot;on the cheap&amp;quot; (cheap being a relative term!) but still achieving an examination of short-term stability (jitter/phase noise) and longer-term stability (both with and in the absence of GPS disciplining)., and still with useful results. For short term stability, the cheapest way I can think of would be to: (1) obtain an ultra-low-phase-noise 10 MHz clock source; Microchip have taken the Vectron product line, and theirs were quite cutting-edge. There&amp;#39;s OX-2040-BEE-2085-10M0000000 which is just over &amp;#163;1k, but MOQ from Mouser is 3. (2) Build (1) into a reference clock source for a spectrum analyzer (your FPC1500 would work for this) (3) Build a relatively sharp 10 MHz crystal filter. This would probably be a couple of weeks exercise, would also need a whole load of crystals so you could bin them. This would require a basic VNA (e.g. FPC1500 or even NanoVNA; in fact NanoVNA might be a better choice for this since there&amp;#39;s two ports). I&amp;#39;ve never built a crystal filter, but have matched a filter, and there&amp;#39;s lots of online information regarding such filter construction since IF filters are a popular thing! (4) Time to add the IQCM-200! Use (3) to provide a notch for it, and feed that into the spectrum analyzer, which is being supplied with the reference from (2). (5) Take a noise measurement away from 10 MHz (e.g. 10 kHz offset) and then some manipulation (primarily adding the filter attenuation value to it) will get the phase noise value. For longer-term stability, one of the possible tests could be: (1) Use two IQCM-200, one with GPS loss, and measure phase difference during 24 hours (e.g. with TinyPFA, see below). This is just a relative measurement, but still useful. Also, it would be good to see what is going on from the data stream that the IQCM-200 apparently outputs. The tinyPFA is free firmware (not open source, unfortunately) that can be installed into a NanoVNA-H4 and used standalone or with TimeLab software , which can provide ADEV charts. All the above would still cost a few $k but better than several $10k! : ) But would easily consume a lot of time and effort.</description></item><item><title /><link>https://community.element14.com/products/manufacturers/iqd-frequency-products/b/blog/posts/disciplined-oscillator-offers-extended-holdover?CommentId=1512dda9-c883-462d-a9a4-c1b08598e184</link><pubDate>Mon, 23 Sep 2024 16:27:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:1512dda9-c883-462d-a9a4-c1b08598e184</guid><dc:creator>shabaz</dc:creator><description>Something weird going on, think it needs Dudley and cstanton expertise.

I wasn&amp;#39;t suggesting that the IQCM-200 was overpriced - merely that it would be hard to judge its performance without something rather better than I have available, and that very few E14 members will have such equipment. The 1.5us hold over is relatively easy to measure but other types of frequency or phase deviation in the 0.02ppb class are a bit more demanding. MK</description></item></channel></rss>
