The DSC1001CL2-020.5972T is a 20.5972 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across its full operating range.
The wide input range means the same oscillator can serve a 1.8V Cortex-M4 or a 3.3V Spartan-6 without a level shifter on the clock input.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead package requires a solder-paste stencil with a 0.15–0.20 mm aperture reduction on the pads to avoid bridging during reflow.
Listed as Active by Microchip — this is a current production part with no announced end-of-life. Procurement can commit to the BOM line without a last-time-buy window or successor migration.
