The DSC6001HE3B-027.1200T is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a fixed 27.12 MHz CMOS clock output.
Operating from 1.71V to 3.63V, this oscillator spans 1.8V and 3.3V logic rails without a secondary regulator — one less BOM line for the power tree. Frequency stability is ±20ppm over the operating range — tight enough for CAN FD, Ethernet, or USB 2.0 clocking where jitter budget is tight.
Housed in a 4-VFLGA package measuring 1.60mm x 1.20mm with a seated height of 0.89mm, this is a compact surface-mount oscillator. The 4-pin LGA footprint requires careful solder-paste stencil design — the small pad area means the thermal relief on the ground pad (if present) must be sized to avoid tombstoning during reflow. Maximum supply current is 1.3mA typical — negligible for most power budgets, but the Enable/Disable pin should be pulled low in sleep to cut draw to near zero.
