Frequently Asked Questions
What output frequency does MX045HS-3C-40M0000 provide and which processor clock domains can it directly drive?
MX045HS-3C-40M0000 outputs a 40 MHz clock signal, which can directly drive microcontroller and FPGA clock inputs that accept 40 MHz references without additional frequency multiplication. This makes it a convenient single-component solution for embedded systems running 40 MHz bus architectures or for designs using PLLs that multiply the 40 MHz input to higher system frequencies.
How does the HS-series designation of MX045HS-3C-40M0000 affect its suitability for industrial temperature range applications?
The HS-series designation indicates a high-stability oscillator design from CTS, typically engineered to maintain tight frequency accuracy across a wide operating temperature range. For industrial designs exposed to temperature swings from -40°C to +85°C, this stability level reduces timing drift, ensuring reliable clock generation for serial communications and data acquisition circuits throughout the full temperature range.
When is MX045HS-3C-40M0000 a better choice than a 40 MHz crystal with external oscillator circuit?
MX045HS-3C-40M0000 is preferable when designers want to eliminate the 3-to-5 component external oscillator circuit — typically a crystal, 2 load capacitors, and sometimes a resistor — reducing BOM count and PCB area. The integrated oscillator also provides a buffered CMOS output signal that directly drives logic inputs, removing the need for an external inverter gate that a bare crystal circuit requires.
For a networking appliance design requiring a 40 MHz reference clock, how does MX045HS-3C-40M0000 support typical procurement lead-time constraints?
CTS MX045HS-3C-40M0000 is available through authorized distributors from stock, allowing procurement teams to avoid extended lead times associated with custom-frequency oscillators. For networking appliance programs with 8-to-12 week PCB fabrication cycles, sourcing a stocked 40 MHz oscillator ensures timing components arrive well before board assembly, preventing schedule delays on clock-critical designs.
