DSC1001DI2-048.0000T Microchip MEMS XO 48 MHz CMOS AEC-Q100

It operates from a 1.8 V to 3.3 V supply and draws a maximum of 7.2 mA, with a Standby (Power Down) function that reduces supply current to 15 µA.

What the frequency stability means for your timing budget

With ±25 ppm frequency stability over the full temperature range, the DSC1001DI2-048.0000T holds the 48 MHz output within ±1.2 kHz of the nominal frequency — sufficient for USB, Ethernet, and general-purpose clocking without external trimming.

Package and footprint considerations for layout

Housed in a 4-SMD, No Lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm, the footprint matches standard quartz XO land patterns — no layout change needed when migrating from a crystal oscillator.
