The DSC1033CI1-035.3280 is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a fixed 35.328 MHz CMOS output from a 3.3V supply rail.
Standby function and low-power profile
Active draw is 3mA typical at 35.328 MHz, a fraction of what a canned crystal oscillator plus buffer would consume at this frequency.
4-SMD package and board-fit note
Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — the same footprint as many 3.2 x 2.5 mm quartz oscillators, so it drops onto an existing PCB layout without a spin.
