The LRT technology from PETERMANN-TECHNIK improves the oscillation behaviour because it is based on LOW ESR Resonator Technology and therefore enables particularly low resistances in the crystal resonator. A low ESR makes it easier for the oscillator circuit to start up and thus enables the crystal resonator to oscillate very quickly, safely and particularly stably, even in oscillator stages with low negative input resistance (Rneg).
The transient behaviour is a critical point in every oscillator circuit. Even if the frequency, load capacitance and tolerance look correct on paper, an unfavourable resonator resistance can lead to problems in the real design. This becomes particularly critical with low supply voltages, low currents, extreme temperatures or miniaturised designs.
LRT oscillating crystals provide additional safety here due to their very low resistance. The resistance-optimised resonator design reduces the load on the oscillator circuit. This stabilises the starting process and considerably reduces the transient response time, resulting in a lower power requirement for the circuit, which significantly reduces the current consumption of the circuit and therefore increases battery life and has a positive effect on current consumption during operation.
Why is PETERMANN-TECHNIK the right partner for LRT oscillating crystals?
PETERMANN-TECHNIK GmbH is the right partner because we understand LRT not just as a product feature, but as a solution for real circuit problems. Developers are not just looking for a crystal, but a clock source that works reliably in the application. This is exactly where our advice comes in.</p
<p>We provide support in selecting the right SMD LRT oscillating crystal, evaluating load capacitance and ESR, offering alternatives to existing products and providing samples. Through 100% testing and a consistent focus on quality, we reduce the risk for our customers and improve the performance of their end products. LRT technology not only supports the customer in their technical performance, but also in their endeavours to achieve sustainability and energy efficiency, thus creating a decisive competitive advantage for the customer.
