Product details

Output is CMOS, making it a direct drop-in for clocking MCUs, FPGAs, and digital logic that expect a square-wave clock from a standard oscillator.

AEC-Q100 qualification and commercial temperature grade

Rated AEC-Q100, this oscillator passed automotive-grade stress tests including temperature cycling and ESD. For a 20 MHz clock, that translates to a maximum frequency error of ±1 kHz — tight enough for UART bit-rate generation and general-purpose processor clocks, though not for precision timing references like GPS or wireless baseband.

Frequently asked questions

What is the exact frequency of DSC1001BC1-020.0000C?

20 MHz.

Does DSC1001BC1-020.0000C require an external load capacitor?

No. As a MEMS oscillator with CMOS output, the DSC1001BC1-020.0000C generates a full-rail square wave internally. Unlike a quartz crystal resonator, it does not need external load capacitors — just a supply bypass cap near the VDD pin per good layout practice.

Can DSC1001BC1-020.0000C replace a standard crystal oscillator?

Yes, if the board expects a 20 MHz CMOS clock input from a standard oscillator. The DSC1001BC1-020.0000C is a drop-in XO replacement — same 4-SMD no-lead footprint, same supply voltage range, same output type. The MEMS base resonator is more shock and vibration tolerant than a quartz crystal, which can be an advantage in automotive or portable equipment.
