Automotive-grade MEMS clock source
The DSC1003DL1-019.2000 is a MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a 19.2 MHz CMOS output with ±50ppm frequency stability across its full operating range.
Supply voltage and current budget
Operating from 1.7V to 3.6V, this oscillator spans the 1.8V and 3.3V logic rails common in automotive and industrial designs — no separate regulator needed for the clock. Active supply current is 6 mA max at 19.2 MHz; the low draw keeps the thermal contribution negligible in the package, even when the oscillator sits next to a hot MCU or transceiver.
Housed in a 4-SMD, no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm, the DSC1003DL1-019.2000 fits tight PCB layouts where every millimeter counts — common in camera modules, telematics, and compact control units.
