The DSC1001CI2-036.0000T is a 36 MHz MEMS-based XO (Standard) delivering a CMOS output. The wide supply range of 1.8V to 3.3V covers common logic rails; the part can be powered from a 3.3V or 1.8V rail without an external regulator, simplifying the power tree.
Supply Current and Standby Function
The standby pin (function: Standby (Power Down)) lets a GPIO or power-management IC disable the oscillator output, cutting clock noise during idle periods.
Frequency Stability and Package
Frequency stability is ±25 ppm, a standard tolerance for general-purpose clocking. The 4-SMD, No Lead package (3.20mm x 2.50mm) is a compact footprint suitable for space-constrained PCBs; the no-lead design reduces parasitic inductance compared to a leaded package.
Microchip lists this part as Active. No pin-compatible second source is recorded; the DSC1001 series is a proprietary Microchip MEMS family. For volume production, a direct factory cross-reference is not available — the BOM should be designed around this single source.
