Applications
The CTS 407F35E016M3840 crystal is used as a precision timing reference in telecommunications equipment, embedded microcontroller clock circuits, and data acquisition instruments that require a stable 16.384 MHz source. Its 30 ppm frequency tolerance and low 3 ppm/year aging rate make it appropriate for systems where long-term clock accuracy is critical, such as GPS receivers and industrial synchronization modules. Low-power IoT nodes and wearable devices also benefit from its 10 µW drive level, which minimizes oscillator circuit current consumption.

Frequently Asked Questions
What is the frequency and frequency tolerance of the CTS 407F35E016M3840 crystal?
The 407F35E016M3840 operates at a fundamental resonant frequency of 16.384 MHz with a frequency tolerance of 30 ppm and a frequency stability of 0.005% over temperature. This 30 ppm tolerance ensures that in a typical embedded system with a 16 MHz clock, the accumulated timing error remains below 0.5 µs per second, which is adequate for UART, SPI, and I2C communication protocols without requiring external frequency calibration.
How does the 3 ppm/year aging specification affect long-term system accuracy for the 407F35E016M3840?
An aging rate of 3 ppm/year means the 407F35E016M3840 drifts no more than 3 Hz per MHz of nominal frequency annually. Over a 10-year product life at 16.384 MHz, the total accumulated drift stays within approximately 30 ppm beyond the initial tolerance, keeping the total error well under 1 minute per year in real-time clock applications. This low aging figure reduces the need for periodic recalibration in deployed industrial or telecom equipment.
Why is the 10 µW drive level of the 407F35E016M3840 important for battery-powered designs?
The 407F35E016M3840 requires only 10 µW of drive power from the oscillator circuit, which translates to less than 3 µA from a 3.3 V supply. This low drive level is critical in IoT sensor nodes and wearables where the crystal oscillator may be active continuously for months on a coin cell. Exceeding the 10 µW drive level can also degrade crystal stability and accelerate aging, so matching the oscillator circuit gain to this specification is necessary for long-term frequency accuracy.
Which system-level timing applications are best suited for the 407F35E016M3840 over a standard 16 MHz crystal?
Applications requiring a 16.384 MHz clock — specifically those using binary-rate communication protocols where the clock must be an exact power-of-two multiple of 32.768 kHz — benefit from the 407F35E016M3840 over a generic 16 MHz crystal. Examples include TDM framing circuits at 2.048 MHz derivatives, GPS disciplined oscillators, and SDLC/HDLC serial controllers. The 30 ppm tolerance and 3 ppm/year aging also favor its use in metering and industrial automation controllers that must comply with IEC timing accuracy specifications.
