Product details

50 MHz MEMS clock source for industrial timing

Unlike quartz-based XOs, the MEMS resonator provides inherent resistance to shock and vibration, making this part a fit for motor drives, outdoor telecom enclosures, and factory-floor controllers where mechanical stress is a concern.

Power budget and standby gating

Supply current is 4 mA typical during active oscillation, while the standby (power-down) function drops consumption to 1 µA maximum — a 4000:1 ratio that allows the oscillator to be gated off between active cycles in battery-operated or energy-harvesting designs. The 1.8V supply rail matches low-voltage core domains in MCUs and FPGAs, eliminating the need for a separate level translator on the oscillator supply.

Sourced through independent distribution; quoted to order against the BOM quantity.

Frequently asked questions

What is the frequency stability of DSC1018DI1-050.0000T?

This is a standard stability grade for general-purpose XOs and provides adequate margin for most MCU clock trees and serial interfaces.

Is DSC1018DI1-050.0000T a direct replacement for standard quartz oscillators?

Yes, it is a functional replacement for a 50 MHz quartz XO in a 4-SMD no-lead package, with the same pinout and CMOS output. The MEMS resonator offers better shock and vibration tolerance than quartz, but the electrical interface is identical — no board spin required.

Can DSC1018DI1-050.0000T be used with a 3.3V supply?

No — this part is specified for a 1.8V supply only. The 1.8V rail is listed as the sole operating voltage; applying 3.3V exceeds the absolute maximum ratings and will damage the device.

What is the standby (power down) current consumption?

The standby current is 1 µA maximum when the part is in power-down mode via the standby function. This allows the oscillator to be disabled between active periods, preserving battery life in intermittently operated systems.
