The enable/disable pin cuts supply current from 35 mA max to 22 mA max when the output is tri-stated — useful for power-cycled subsystems in telematics or ADAS cameras that sleep between ignition cycles. ## MEMS vs quartz — the reliability edge The MEMS base resonator inherently withstands higher shock and vibration than a quartz crystal — no mechanical fracture risk under 50,000 g shock, no frequency jump from board flex. The ±50 ppm stability covers most precision clocking needs; if your design requires tighter ±25 ppm, the DSC1121 family offers that variant, but the ±50 ppm grade is the standard option for Ethernet, CAN, and general-purpose microcontroller clocks. ## Package and PCB footprint The 5.00mm x 3.20mm 6-SMD no-lead package matches the common 5.0 x 3.2 mm oscillator land pattern used across the industry. The 0.90 mm seated height fits tight mezzanine stacks. Surface-mount reflow profile follows standard JEDEC J-STD-020 for MSL — no special handling beyond normal moisture-sensitive assembly.","metaTitle":"DSC1121BI1-150.0000 MEMS Oscillator 150 MHz AEC-Q100","metaDescription":"Microchip DSC1121BI1-150.0000 XO (Standard) MEMS oscillator, 150 MHz CMOS output, ±50 ppm stability, AEC-Q100 qualified, -40°C to 85°C.
