The DSC1001AE1-125.0000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 125 MHz CMOS output with ±50 ppm frequency stability.
The standby feature is a logic-level pin that shuts down the output and internal PLL, letting the system clock gate without a separate load switch.
Package, footprint, and temperature grade
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard 7x5 mm oscillator footprint that matches many quartz XO pads, simplifying drop-in replacement. For an AEC-Q100 qualified part, this limits deployment to cabin or controlled environments, not under-hood or engine-bay zones where -40°C to +125°C is typical.
