Supply range and current draw for rail budgeting
Supply voltage spans 1.7V to 3.6V — the oscillator runs directly off a 1.8V, 2.5V, or 3.3V rail without an external LDO, simplifying power distribution on mixed-voltage boards. Maximum active supply current is 6 mA at 20 MHz, a low enough draw that the oscillator adds negligible heat to a dense PCB layout.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this is a standard 3.2 x 2.5 mm oscillator footprint — compatible with many quartz XO pads, though the MEMS die has different decoupling needs.
Active production status and sourcing posture
Product status is Active — Microchip continues to manufacture the DSC1003CL2-020.0000T, and it remains open for new designs. No stock-holding claim — availability confirmed at RFQ.
