MEMS oscillator for harsh environments
The DSC1121AM2-050.0000: This 50 MHz XO uses a MEMS resonator instead of a quartz crystal, giving it better shock and vibration tolerance than a conventional crystal oscillator — relevant for engine-bay electronics or downhole instrumentation where the board sees sustained g-loading. AEC-Q100 qualification confirms the part passed the automotive reliability stress suite: temperature cycling, ESD, and latch-up testing. Combined with the -55 to +125 °C operating range, this oscillator is suited for under-hood ECUs, ADAS sensor modules, and defence telemetry that must start and hold frequency across the full military temperature band.
Supply rail and output compatibility
The CMOS output swings rail-to-rail, so it drives most MCU and FPGA clock inputs directly; no level translation needed. Maximum supply current is 35 mA when enabled and 22 mA when disabled. The Enable/Disable function lets a system power-down the oscillator in sleep mode, cutting current draw by roughly 13 mA — useful in battery-operated or energy-harvesting designs where every milliwatt counts.
It is a standard catalog part in the DSC1121 series, suitable for new designs and production ramp.
The 6-SMD no-lead exposed pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The exposed pad under the package provides a thermal path to the PCB — a solid ground-plane via pattern under the pad improves heat dissipation and reduces frequency drift under load.
