The oscillator accepts a 2.5V to 3.3V supply rail, so it can run from a 3.3V or 2.5V regulator without an extra LDO. Maximum supply current is 7.5 mA at 48 MHz — a 360 µW draw at 3.3 V, which leaves headroom in the power budget for the rest of the digital load.
The 4-VDFN exposed pad package (7.00 mm x 5.00 mm, 0.90 mm seated height) provides a low-profile footprint with a thermal pad that helps conduct heat to the PCB ground plane.
The DSC1502AI3A-48M00000T is an active-production part from Microchip Technology.
The DSC1501 is a different variant within the same DSC150X MEMS oscillator family. The key difference is the output frequency and stability grade — the DSC1502AI3A-48M00000T is a 48 MHz part with ±20 ppm stability, while the DSC1501 covers other frequencies or tolerances. Confirm the exact order code for your BOM position; the two are not drop-in equivalents without verifying the frequency and stability spec.
Yes. The part includes a Standby (Power Down) function. When the standby pin is asserted, the oscillator stops and the supply current drops to 1.8 µA typ, preserving battery life in intermittently active systems.
The frequency stability is ±20 ppm.
