Since the early 1980s, the Ethernet standard has evolved from a simple communication method between computer networks to the most widely used protocol in industrial communication. Copper cables, whether 2-pair for Fast Ethernet or 4-pair for Gigabit Ethernet, form the backbone of many corporate and industrial networks. The introduction of Single Pair Ethernet (SPE) technology, inspired by developments in the automotive industry, is now opening up completely new fields of application. This technology makes it possible to replace traditional analog sensor applications or industrial bus systems with more efficient solutions.
Single Pair Ethernet (SPE) provides the necessary infrastructure for the Industrial Internet of Things (IIoT). With SPE, Ethernet can communicate from the cloud to the field level in a space- and cost-efficient manner for the first time. Single Pair Ethernet describes the transmission of Ethernet via just one pair of copper wires and, in addition to data transmission via Ethernet, also enables a simultaneous power supply to end devices via PoDL – Power over Data Line. Previously, this required two pairs of wires for Fast Ethernet (100MB) or four pairs for Gigabit Ethernet. SPE now opens up completely new possibilities and fields of application for Industrial Ethernet.
Innovative clocking solutions for SPE technology
25 MHz SMD oscillating crystals are essential for clocking SPE ICs. Our customers use our 25 MHz crystals in different housing versions, which are used with SPE ICs from a wide range of manufacturers.
All our SMD resonant crystals are based on our unique, patented LRT resonator design. Quartz resonators based on our LRT technology are known for their innovative resonator design, outstanding quality and performance. These crystals are also characterized by a very long service life and reliability, thus guaranteeing many years of trouble-free operation of the corresponding applications. Particularly noteworthy is the continuous and reliable availability of our SMD crystals – even during the challenging times of the corona pandemic.
Our SMD crystals offer an excellent price-performance ratio and therefore make a significant contribution to increasing the efficiency and productivity of our customers.
Due to the very low resistance of our LRT oscillating crystals our innovative 25 MHz LRT crystals for Single Pair Ethernet applications have a significantly faster and safer transient response, which reduces the power consumption of the circuit and results in lower power requirements. In this way, we support our customers not only in their technical performance, but also in their efforts to achieve sustainability and energy efficiency. The highest level of product safety 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 quartz crystals. This means that we can always supply the same LRT resonator design for the corresponding product purchased from us, for many years to come. Excellent quality and product performance is guaranteed by the 100% testing of the SMD LRT resonator crystals we supply. This is because everything from the raw quartz material to the end product is under the control of our quality assurance department. Pure quality promise, for very durable SMD LRT oscillating crystals.
