50 MHz MEMS oscillator – industrial temperature, low power
The DSC1033DI1-050.0000 is a 50 MHz XO (Standard) from Microchip's PureSilicon™ MEMS oscillator family, delivering a CMOS output at 3.3V with ±50 ppm frequency stability.
Microchip lists the DSC1033DI1-050.0000 as Obsolete. No official second-source or direct pin-compatible successor is recorded from the original manufacturer. The 4-SMD, no-lead package (2.50 mm x 2.00 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint. A board spin would be required to migrate to a different package or pinout alternative.
