The DSC1003CL1-019.2000T is a 19.2 MHz MEMS-based oscillator in the DSC1003 series from Microchip Technology, with an AEC-Q100 rating that makes it a qualified part for automotive and industrial designs — not just 'capable' but documented with the PPAP data an OEM auditor expects. The CMOS output interfaces directly with most MCU clock inputs without external level translation, and the supply voltage range of 1.7V to 3.6V lets it run on the same rail as 3.3V, 2.5V, or 1.8V logic — no separate LDO needed for the clock source.
19.2 MHz reference with standby power-down
At 19.2 MHz, this oscillator serves as a common reference for MCU clock trees and CAN transceiver timing. Active current draw is 6 mA max at the rated frequency, which is low enough that thermal dissipation in the 4-SMD package is negligible even at 105°C ambient.
Surface-mount footprint and tape-and-reel delivery
The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight ECU board layouts.
