Frequently Asked Questions
How stable is the VCC1-A3F-16MHZ output frequency over temperature in an industrial application?
The VCC1-A3F-16MHZ maintains a frequency stability of ±25 PPM across its full -40°C to +85°C operating range. This means that at 16 MHz the frequency deviation stays within 400 Hz, which is well within tolerance for UART communication, SPI interfaces, and most microcontroller clock requirements in industrial control systems.
What supply voltage and load capacitance does the VCC1-A3F-16MHZ require for proper operation?
The VCC1-A3F-16MHZ requires a 5 V supply voltage and is specified for a 15 pF load capacitance. These values align with standard TTL and CMOS logic levels, making it straightforward to drive typical microcontroller clock inputs or FPGA clock pins without additional buffering or impedance-matching components in most 5 V system designs.
In which clock-sensitive design scenarios does VCC1-A3F-16MHZ offer an advantage over a passive crystal?
Unlike a passive crystal that requires external load capacitors and an oscillator circuit, the VCC1-A3F-16MHZ is a fully integrated oscillator module delivering a buffered 16 MHz output directly. This eliminates pierce-oscillator layout sensitivities, reduces startup time to under 10 ms, and simplifies PCB design—advantages that matter in space-constrained industrial controllers and single-board computers needing deterministic boot behavior across the -40°C to +85°C range.
