MEMS oscillator at 20 MHz — what it replaces on the BOM
The DSC1033CC1-020.0000T is a MEMS-based XO from Microchip's PureSilicon™ series, delivering a 20 MHz CMOS output from a 3.3V rail. The MEMS resonator means no quartz crystal matching network — the oscillator is self-contained in a 3.20 mm x 2.50 mm 4-SMD no-lead package.
Standby power-down — when the clock tree sleeps
In normal operation the oscillator draws 3 mA typical — the standby mode preserves battery life in intermittently powered systems like IoT edge nodes or handheld instruments.
