Which Frequency Control Products Are Best Suited for Electronic Locking Systems, RFID Readers, and BLE Access Solutions?
Electronic locking cylinders, RFID readers, and mobile access systems must operate reliably for many years. In addition to the Battery, Frequency Control Products and Real-Time Clocks (RTCs) ensure that microcontrollers, wireless modules, and timing functions operate with precision and maintain stable communication. As a result, selecting the right components has a direct impact on power consumption, communication range, time accuracy, and the overall reliability of an access control system.
Wireless Quartz Crystals for RFID, NFC, and BLE Applications
Modern access control systems increasingly rely on wireless communication. Whether using RFID cards, NFC-based access, or smartphone-based mobile access solutions, stable wireless connections require a reliable frequency reference.

RTCs for Time Profiles, Event Logging, and Time Tracking
RTCs, or Real-Time Clocks, are a key component of modern access control systems, providing local timekeeping functionality. They enable reliable time and calendar management and provide the time base required to accurately process time-dependent access permissions, event logs, and access schedules.
This is particularly important for systems that must operate without a permanent network connection. In such applications, a local RTC ensures that access events continue to be recorded with accurate time stamps and that time-based permissions can be evaluated reliably.
Suitable Jauch Products:
- RTC Modules with Real-Time Clock, Calendar, Alarm, and Wake-Up Functions
- Solutions for Mains-Powered Systems with Backup Battery as well as for Power-Optimized Applications
- Modules with an Integrated 32.768 kHz Time Base to Reduce the Number of External Components
Advantages:
- Reliable Local Time and Date Management
- Accurate Time Stamps for Access and Event Logs
- Support for Time-Based Access Permissions and Access Schedules
- Low Power Consumption During Backup Operation
- Simplified Circuit Design Through the Integration of RTC, Oscillator, and 32.768 kHz Quartz Crystal Functions
Oscillators for Microcontrollers and Wireless Modules
Oscillators provide a ready-to-use clock signal for microcontrollers, security ICs, and wireless modules. They simplify system design and ensure reliable communication between individual system components.
Suitable Jauch Products:
- JO Series Quartz Oscillators
- Available in Various Frequency Ranges and Package Sizes
Advantages:
- Stable Clock Signals for Embedded Systems
- Reliable Wireless Communication
- High Ease of Integration
- Suitable for Energy-Efficient Applications
TCXOs for Applications with Enhanced Stability Requirements
Access control solutions are often deployed in outdoor environments, industrial facilities, and other demanding settings. Temperature variations can affect frequency stability. Temperature-Compensated Crystal Oscillators (TCXOs) compensate for these effects and provide enhanced operational reliability.
Suitable Jauch Products:
- JT Series Temperature-Compensated Crystal Oscillators (TCXOs)
Advantages:
- High Frequency Stability Across the Operating Temperature Range
- Enhanced Communication Reliability
- Reliable Operation Under Changing Environmental Conditions
- Suitable for Demanding Wireless Applications
What Developers Should Consider When Selecting Components
The selection of a Frequency Control Product should not be based solely on the required frequency. Equally important are the specific requirements of the application and the operating conditions the product will encounter in the field.
Key Selection Criteria:
- Wireless Standard (RFID, NFC, BLE)
- Available Installation Space
- Power Consumption
- Operating Temperature Range
- Frequency Stability
- Long-Term Reliability
- Required Battery Life
- Requirements for Time Stamps, Time Tracking, and Access Schedules
Conclusion: Reliable Access Control Starts with the Right Timing
Whether it is an electronic locking cylinder, RFID reader, or BLE-based mobile access solution, reliable access control depends on the interaction of multiple timing components. JXS-WA Series Wireless Quartz Crystals support wireless communication, JTX Series Tuning Fork Crystals provide a precise time base, RTCs handle timekeeping and calendar functions, while JO Series Quartz Oscillators and JT Series TCXOs ensure stable clock signals. The optimal selection depends on the wireless standard, available installation space, power requirements, and the application’s demands for time accuracy and long-term stability.
By selecting the right combination of Quartz Crystal, RTC, and Oscillator during the development phase, designers can establish the foundation for long-lasting, energy-efficient, and reliable access control systems. Particularly in Battery-powered solutions, optimally matched timing components play a key role in reducing maintenance requirements and ensuring dependable operation over many years.
