The DSC1001AL2-050.0000T is a 50 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 family, delivering CMOS output with ±25 ppm frequency stability across the full -40 to 105°C industrial-automotive temperature range. The MEMS resonator inherently withstands higher vibration and mechanical shock than a quartz blank, which is a practical advantage on engine blocks, transmission controllers, and chassis-mounted PCBs.
Operating from 1.8V to 3.3V, this oscillator can be powered from a 1.8V core rail or a 3.3V I/O rail without a separate LDO — the wide range covers both without a level translator on the output.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — this is a standard 7x5 mm oscillator footprint, pin-compatible with many quartz XOs of the same size. Surface-mount on a standard reflow profile; the exposed pad is not electrically required but provides a thermal path if the application demands it.
