IQD的IQXT-200和IQXT-210 溫補(bǔ)晶振TCXO現(xiàn)在提供-40至105°C的擴(kuò)展工作溫度范圍，具有異常緊密的穩(wěn)定性。這種寬溫度范圍特別適用于暴露在極端環(huán)境和高溫下的應(yīng)用，例如消防員，石油和天然氣行業(yè)以及物聯(lián)網(wǎng)的便攜式無線電系統(tǒng)。然而，不僅環(huán)境溫度需要振蕩器高達(dá)105°C，而且在外殼應(yīng)用中放置在振蕩器附近的其他組件的自加熱也需要振蕩器。
IQXT-200采用7.0 x 5.0 mm封裝，在此寬溫度范圍內(nèi)穩(wěn)定性為±50 ppb或±280 ppb。IQXT-210采用較小的5.0 x 3.2 mm封裝，現(xiàn)在可在-40至105°C范圍內(nèi)提供±280 ppb的穩(wěn)定性。四個(gè)可用的標(biāo)準(zhǔn)頻率是10.0 MHz, 19.2 MHz, 20.0 MHz和38.88 MHz，但可根據(jù)要求提供其他頻率。
電流消耗比標(biāo)準(zhǔn)ocxo低90%
兩種型號(hào)都指定具有3.3 V供電電壓和HCMOS輸出，而最大電流僅為10 mA。這些tcxo的當(dāng)前功耗比可比的標(biāo)準(zhǔn)ocxo低90%。此外，由于技術(shù)功能，ocxo無法在-40至105°C的擴(kuò)展溫度范圍內(nèi)提供。這就是為什么IQXT-200和IQXO-210為極端溫度條件下的應(yīng)用提供理想的解決方案，在這些條件下，嚴(yán)格的穩(wěn)定性是必不可少的。
這些振蕩器還可以指定包括±8ppm min的拉范圍，其頻率可以通過各種應(yīng)用的固定數(shù)量進(jìn)行調(diào)整，這也允許遠(yuǎn)程應(yīng)用。
IQXT-200和IQXT-210主要用于通信和物聯(lián)網(wǎng)應(yīng)用。憑借嚴(yán)格的穩(wěn)定性，它們?yōu)樾⌒头涓C、光纖網(wǎng)絡(luò)(PON)、網(wǎng)絡(luò)路由器和交換機(jī)、5G基站、回程基礎(chǔ)設(shè)施、Wi-Fi和各種其他類型的通信等應(yīng)用確保了穩(wěn)定的時(shí)序。
這兩種型號(hào)都符合RoHS標(biāo)準(zhǔn)，回流焊兼容，并提供磁帶和卷軸。
IQD’s IQXT-200 and IQXT-210 TCXOs now offer an extended operating temperature range of -40 to 105°C with exceptionally tight stability. This wide temperature range is particularly appropriate for applications that are exposed to extreme environments and high temperatures such as portable radio systems for fire fighters, oil & gas industries and IoT. However, it is not only the ambient temperature that requires oscillators up to 105 °C, but also the self-heating of other components that are placed close to the oscillator in the application in an enclosure.
The IQXT-200 is available in a 7.0 x 5.0 mm package with a stability of ±50 ppb or ±280 ppb over this wide temperature range. The IQXT-210, in the smaller 5.0 x 3.2 mm package, is now offered with a stability as tight as ±280 ppb over -40 to 105°C. The four standard frequencies available are 10.0 MHz, 19.2 MHz, 20.0 MHz and 38.88 MHz however, others may be available upon request.
Current Draw 90 % less than standard OCXOs
Both models are specified with a 3.3 V supply voltage and an HCMOS output, while having a current draw of only 10 mA max. The current draw of these TCXOs is 90 % less than comparable standard OCXOs. Moreover, due to technical functionality, OCXOs cannot be offered at the extended temperature range of -40 to 105 °C. This is why the IQXT-200 and IQXO-210 offer the ideal solution for applications within extreme temperature conditions where tight stabilities are essential.
These oscillators can also be specified to include a pulling range of ±8ppm min. and their frequency can be adjusted by a fixed amount for various applications, which also allows for remote applications.
The IQXT-200 and IQXT-210 are primarily designed for communication and IoT applications. With the tight stability, they secure stable timing for applications such as small cells, Fibre Optic Networking (PON), Network Routers and Switches, 5G Base Stations, Backhaul Infrastructure, Wi-Fi and various other kinds of communication.
Both models are RoHS compliant, reflow soldering compatible and supplied on Tape & Reel.
