36 MHz MEMS oscillator — what it clocks and where it sits
The DSC1033DI1-036.0000 is a 36 MHz XO (Standard) oscillator built on Microchip's PureSilicon™ MEMS resonator technology, delivering a CMOS output at 3.3 V supply.
Standby power-down — the 1 µA sleep edge
For a battery-powered sensor node that wakes once per minute to transmit, the oscillator's own draw in sleep is negligible — the coin cell's self-discharge dominates the shelf life, not the clock.
Microchip lists the DSC1033DI1-036.0000 as Obsolete. A board-spin to a current-production MEMS oscillator (same 4-SMD, no-lead footprint, same 3.3 V supply) is the migration path for new designs.
4-SMD no-lead — board-fit checklist
The 2.50 mm × 2.00 mm × 0.90 mm 4-SMD, no-lead package uses a standard land pattern for 4-pin MEMS oscillators. No thermal pad or exposed paddle — the decoupling cap sits close to the supply pin on the same layer. The 0.90 mm seated height clears most enclosure constraints in portable or compact assemblies.
