MEMS clock source for automotive electronics
The DSC1001DE2-148.3516T is a MEMS-based XO (standard oscillator) from Microchip's DSC1001 series, delivering a fixed 148.3516 MHz CMOS output.
It covers cabin electronics, infotainment clusters, and telematics boxes, but not engine-bay or exterior sensors where -40°C to 125°C would be required. The AEC-Q100 grade applies to this temperature band — confirm the specific AEC-Q100 grade (e.g., Grade 3) in the full datasheet if your thermal profile extends below -20°C.
Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. The compact footprint suits space-constrained automotive modules; the no-lead design reduces parasitic inductance compared to a through-hole crystal can, which helps maintain signal integrity at 148.3516 MHz. Surface-mount mounting — standard reflow profile for MEMS oscillators; no special bake-out required unless the moisture sensitivity level (MSL) on the reel label indicates otherwise.
