What are the technical specifications to consider when selecting a crystal oscillator?

Compared to crystals, the most prominent feature of crystal oscillators is that they directly output a clock signal as soon as power is applied. The clock signal levels also vary widely, with supported levels including TTL, CMOS, HCMOS, LVCOMS, LVPECL, and LVDS. When selecting a crystal oscillator, you should choose one that matches the required clock signal level.

High-stability temperature-compensated crystal oscillators – the best choice for satellite positioning modules.

In fields with strict size requirements, such as smart wearable devices, drones, and portable positioning terminals, miniaturized positioning modules are needed. The YSO510TP can meet the demand for miniaturized positioning modules, offering a minimum package size of 2.0 x 1.6mm, which helps achieve miniaturization and compact design of devices and improves the overall integration of the equipment.

Measures to prevent crystal oscillator aging

How much do you know about crystal oscillator aging? Crystal oscillators undergo anti-aging treatment during the manufacturing process. There are two types of crystal oscillators: crystal resonators and crystal oscillators. During production, both types require anti-aging treatment, but these treatments differ.

Ultra-low power consumption YSN8563MS RTC + YST310S crystal oscillator, the perfect combination for smart door lock timing.

From home fingerprint locks to apartment smart locks, from hotel room card systems to commercial access control, the "YSN8563MS RTC + YST310S crystal oscillator" has become a key tool for smart lock manufacturers to break into the market, thanks to its core advantages of "functional integration, low power consumption, and precise reliability."

Advantages and disadvantages of active crystal oscillators and passive crystal oscillators

Communication equipment (5G base stations, optical modules, frequency ≥100MHz). Precision instruments (atomic clock synchronization, TCXO/OCXO temperature-compensated crystal oscillators). Complex environments: industrial control (vibration resistant, wide temperature range -40℃ to +125℃). Direct drive: FPGA global clock, high-speed SerDes interface (e.g., 25Gbps Ethernet).

The effect of temperature on RTC crystal oscillators

The main matching crystal oscillator for RTC is a 32.768kHz tuning fork crystal oscillator. The frequency stability of the tuning fork crystal oscillator is significantly affected by temperature. With 25℃ as the reference, the further the temperature deviates, the greater the frequency drift. For example, the temperature drift can reach -49ppm at -10℃ or 60℃, which leads to increased timing errors.
