The DSC1004CI2-033.0000: This is a 33 MHz MEMS-based oscillator (XO) delivering a CMOS output — no external quartz crystal or load capacitors needed on the board.
The supply voltage accepts 1.8V to 3.3V — a single part covers 1.8V, 2.5V, and 3.3V logic rails without a separate regulator.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Surface-mount reflow compatible; the small footprint leaves room for decoupling caps on a dense PCB.
Yes, it is a drop-in functional replacement for any 33 MHz quartz XO with CMOS output in a 4-pin SMD package. The MEMS resonator is more robust under shock and vibration, and the ±25 ppm stability matches or exceeds many quartz parts. No external load capacitors are needed.
