Our 25 MHz crystals, based on the exclusive LRT technology, are not only inexpensive, but also popular for their excellent performance, exceptional durability and functional reliability. Each of our products is 100% tested! In this way, we also support our customers in their quest for sustainability and energy efficiency.
25 MHz AEC-Q200 SMD oscillating crystals are essential for clocking automotive SPE ICs. The 25 MHz AUTOMOTIVE LRT resonant crystals in various housing versions have established themselves in our customers’ applications. Quartz resonators based on LRT technology are popular for their extremely innovative resonator design and for their outstanding quality and performance. Based on the 100% testing process, our LRT crystals are also characterized by their very long service life and reliability, thus guaranteeing many years of trouble-free operation of the corresponding automotive applications.
Due to the very high production volumes, all of the frequency-generating components we supply offer an excellent price-performance ratio and therefore make a significant contribution to reliable costing and long-term cost efficiency.
What is the technical advantage of the LRT quartz crystals, apart from the very low price?
Due to the very low resistance of the LRT resonant crystals, a significantly faster and safer transient response is made possible in the circuit of the Single Pair Ethernet ICs, even over the automotive temperature range of -40/+125°C, so that the current consumption of the circuit is reduced and a lower power requirement results. The LRT oscillating crystals therefore not only support the customer in their technical performance, but also in their pursuit of sustainability and energy efficiency. The highest level of product reliability from delivery batch to delivery batch is of course guaranteed, as only quartz resonators developed and manufactured in-house are used in our SMD LRT clock generators. This means that we can always supply the same LRT resonator design for the corresponding approved product for many years to come. Excellent quality and product performance is guaranteed by 100% testing of the SMD LRT resonator crystals supplied. This is because everything from the raw quartz material to the end product is under the control of our own quality assurance department. Pure quality promise, for very durable SMD LRT oscillating crystals.
Which housing versions/quartz specifications are currently preferred by our automotive customers?
Wherever possible, our customers use SMD crystals in 4-pad ceramic housings with dimensions of 3.2×2.5mm (SMD03025/4 crystal series), including in automotive applications. The SMD03025/4 oscillating quartz series is currently the most cost-effective quartz series available! If this housing is too large for the application in question, the next smallest top-selling quartz crystal has dimensions of 2.0×1.6mm, or for very small applications the quartz frequency of 25 MHz is also available in a ceramic housing with dimensions of 1.6×1.2mm. With regard to the crystal parameters, the frequency tolerance of ±20 ppm at +25°C and the temperature stability of ±50 ppm over the automotive temperature range of -40 to 125°C have proven to be ideal for SPE automotive applications. The customer usually opts for a quartz load capacitance of 12pF (the quartz is connected using external capacitances of 18pF to GND), but other load capacitances are of course also available, such as 8pF or 10pF.
SMD top-seller oscillating crystals in the ceramic housings 3.2×2.5mm/4pad, 2.0×1.6mm/4pad or 1.6×1.2mm/4pad are of course also available in other versions. Our exclusive product configurators are available to developers or purchasers, so that the desired products can be configured in no time at all, inquired about immediately or samples can be requested. PETERMANN-TECHNIK GmbH can also support the customer with a wide range of design-in activities during the development phase and series production.
