MEMS oscillator for timing applications
The DSC1033CI1-007.3728T is a MEMS-based XO oscillator from Microchip's PureSilicon™ series, delivering a 7.3728 MHz CMOS output at 3.3V with ±50ppm frequency stability.
Microchip lists the DSC1033CI1-007.3728T as Obsolete. Available through independent distribution in lot-specific quantities. A board-level redesign may be required to migrate to a current-production oscillator.
Housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a common footprint for MEMS oscillators. Surface-mount assembly; the 4-pad layout is straightforward for standard reflow processes. No thermal pad or via-in-pad required.
