The DSC1001BI3-022.5792 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 22.5792 MHz CMOS output with ±20 ppm frequency stability.
Supply voltage flexibility and power-down standby
The oscillator accepts a supply voltage from 1.7V to 3.6V, which lets it run directly from a 1.8V, 2.5V, or 3.3V rail without an external LDO — a BOM simplification for multi-voltage systems. Normal operation draws a maximum of 8 mA, a figure that includes the MEMS driver and CMOS output buffer.
Housed in a 4-VDFN package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, this oscillator fits standard 4-pin oscillator land patterns. The surface-mount package is compatible with reflow soldering profiles typical for automotive PCBs. The 0.90mm height is low enough for mezzanine card or stacked PCB assemblies where clearance is tight.
