Product details

The DSC1033DI1-014.7456T is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 14.7456 MHz CMOS output from a 3.3V supply rail.

Microchip lists the DSC1033DI1-014.7456T as Obsolete. A board-spin to a current-production MEMS oscillator (same 2.50 mm x 2.00 mm 4-SMD footprint, same 3.3V supply) is the cleanest long-term fix; the replacement search should match the 14.7456 MHz frequency, CMOS output, and ±50 ppm stability.

Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits tight-profile designs.

Frequently asked questions

Is the DSC1033DI1-014.7456T obsolete?

Yes, Microchip lists it as Obsolete. No official replacement part number is published.

What is the frequency and output type of the DSC1033DI1-014.7456T?

It is a 14.7456 MHz XO (Standard) with CMOS output. The 3.3V supply rail and ±50 ppm frequency stability make it a direct drop-in for many microcontroller or FPGA reference-clock sockets.
