148.5 MHz LVDS MEMS oscillator with AEC-Q100 automotive grade
AEC-Q100 qualified — this is not an industrial part dressed up for automotive; the qualification covers the reliability stress and temperature grade demanded by under-hood and cabin electronics. The OEM auditor will ask for PPAP, and this part supports that documentation chain. Supply voltage spans 2.25V to 3.63V, covering common 2.5V and 3.3V rails without an external regulator.
Housed in a 6-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90 mm. Surface-mount on standard FR-4; the 6-pad footprint matches common MEMS oscillator land patterns — no buried vias or microvias required. The MEMS base resonator eliminates quartz crystal aging and shock sensitivity — relevant for engine-bay and chassis-mounted ECUs that see vibration and thermal cycling.
Microchip Technology supplies this under the DSC1123 series. The base product number DSC1123 covers multiple frequency, stability, and output options. For volume or blanket orders, the exact DSC1123BI5-148.5000 suffix locks in the 148.5 MHz frequency, ±10 ppm stability, and LVDS output.
