Product details

MEMS oscillator at 50 MHz — what this part is

The DSC1033AE1-050.0000T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 50 MHz CMOS output from a 3.3V supply rail.

Microchip lists the DSC1033AE1-050.0000T as obsolete. For a new design, consider the active DSC1000 series from Microchip, which shares the same 4-SMD package and 3.3V supply but uses a different MEMS die — pin compatibility should be verified against the datasheet before committing a board spin.

Package and mounting — 4-SMD no-lead exposed pad

The 4-SMD, no-lead exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Reflow profile follows standard JEDEC J-STD-020 for MSL level 1, so no bake is needed before assembly if the reel seal is intact.

Frequently asked questions

Is the DSC1033AE1-050.0000T compatible with 3.3V systems?

Yes, the supply voltage is 3.3V, and the CMOS output swings rail-to-rail, so it interfaces directly with 3.3V logic families without level translation.

What is the frequency stability of the DSC1033AE1-050.0000T?

The oscillator holds ±50 ppm frequency stability over the -20°C to 70°C operating range. This is typical for a standard XO — sufficient for UART baud-rate generation and general-purpose clocking, but not tight enough for precision timing like Ethernet or GPS.
