DSO221SR

DSO221SR is a miniaturized SPXO crystal oscillator designed for ultra-low-frequency to high-frequency applications, featuring a compact 2.5×2.0×0.9mm package. It covers an ultra-wide frequency range of 0.2 to 125.0 MHz, including the standard 32.768kHz RTC frequency point. Supporting a wide voltage input range of 1.6 to 3.6V with an integrated internal voltage regulator, it is compatible with both button cell and lithium battery power supplies. With a typical power consumption of only 1.5mA (at high frequencies) and standby current below 0.5μA, the DSO221SR combines ±30ppm industrial-grade wide temperature stability (-40℃ to +85℃) and optional differential signal output. In applications such as smart wearable devices (e.g., micro medical patches, hearing aids), IoT sensor nodes (e.g., soil moisture monitors), and low-power MCU systems, the DSO221SR can simultaneously meet the timing precision requirements for RTC real-time clocks, sensor sampling synchronization, and wireless communication protocols (e.g., BLE 5.0). Its interference-resistant metal package design effectively mitigates interference in complex electromagnetic environments.

In the automotive electronics sector, KDS crystal oscillators boast remarkable advantages. Their automotive-grade temperature-compensated crystal oscillators have obtained AEC-Q200 certification, maintaining a frequency stability of ±1ppm within a temperature range of -40°C to +125°C. They are resistant to 50G vibrations, providing precise timing for ADAS (Advanced Driver Assistance Systems) and more. With low-noise design, they reduce signal interference in in-vehicle entertainment systems, and their ultra-small packaging saves space. When used in body control modules and battery management systems, they demonstrate low failure rates after high-temperature aging tests, support high-temperature reflow soldering, and their voltage-controlled crystal oscillators can handle voltage fluctuations while consuming low power. As a distributor, MANDU integrates the features of KDS crystal oscillators with its own storage products to offer customers integrated solutions for vehicle clock synchronization and storage, thereby facilitating the intelligent and secure upgrading of automotive electronics.
