Automotive-grade MEMS clock source for harsh environments
The DSC1001CL1-012.0000T is a 12 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm absolute pull range.
Supply flexibility and standby power savings
A single supply voltage from 1.8V to 3.3V lets this oscillator serve 1.8V MCU cores and 3.3V peripheral buses on the same BOM line.
Package and reflow considerations for the 4-VDFN
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator uses a standard surface-mount footprint. Check the MSL rating before reflow; the small 4-lead package is less prone to tombstoning than larger QFN parts, but pad geometry and solder-paste volume still matter for coplanarity.
