Product details

50 MHz MEMS oscillator with ±10 ppm stability

AEC-Q100 qualification means this part has passed automotive-grade reliability stress tests — suitable for under-hood or cabin electronics where temperature cycling and vibration are routine. Supply voltage spans 1.8V to 3.3V, covering common logic rails without an external level translator.

Enable/Disable function and power budget

The Enable/Disable function lets the system gate the clock output — useful for power-save modes or peripheral clock gating without removing the supply rail. Active supply current is 7.2 mA max; disabling the output drops consumption to 15 µA max, which matters for battery-operated equipment that sleeps between operations.

Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — a compact footprint that fits tight PCB layouts without requiring through-hole clearance. Surface-mount assembly with standard reflow profiles; the MEMS resonator eliminates the crystal blank and its associated load-capacitance matching, simplifying the BOM.

Frequently asked questions

What is the frequency stability of DSC1001BL5-050.0000?

This is tighter than the typical ±25 ppm or ±50 ppm oscillators, making it suitable for timing-sensitive interfaces like USB or 100BASE-TX.

What does the Enable/Disable function do on this oscillator?

The Enable/Disable pin allows the output to be tri-stated (high-impedance) while the oscillator core remains powered. When disabled, the supply current drops to 15 µA max, versus 7.2 mA max when active. This is useful for power gating in multi-clock systems without cycling the supply.
