The Enable/Disable function lets the output be tri-stated, pulling supply current from 35 mA max to 22 mA max in disable — useful for power-sequenced or fault-tolerant clock trees. This is a design-in grade part, not a last-time-buy candidate. No stock-holding claim is made; each order is quoted to order. ## Package and mounting for 6-SMD Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm max. The surface-mount footprint is standard for this form factor; the exposed pad requires a thermal via pattern under the package for proper solder joint inspection and thermal relief.","metaTitle":"DSC1121AE5-033.8688 MEMS XO – 33.8688 MHz, AEC-Q100, CMOS","metaDescription":"Microchip DSC1121AE5-033.8688 MEMS oscillator: 33.8688 MHz, ±10 ppm, 2.25-3.6 V, AEC-Q100, CMOS output, Enable/Disable.

This qualifies it for use in automotive electronic systems where the supplier requires PPAP documentation."},{"question":"Does the DSC1121AE5-033.8688 have an enable/disable function?","answer":"Yes, the Enable/Disable function is standard. When disabled, the output goes high-impedance and supply current drops from 35 mA max to 22 mA max, useful for power management in multi-clock systems."},{"question":"Is the DSC1121AE5-033.8688 a MEMS oscillator?","answer":"Yes, the base resonator is MEMS, not quartz. MEMS oscillators offer better shock and vibration tolerance, faster startup, and typically shorter lead times compared to quartz-based XOs.
