The MEMS base resonator means this oscillator is less susceptible to vibration and shock than a quartz equivalent, and it starts up faster — a practical advantage in portable or ruggedized equipment where a quartz can may fail or drift.
Maximum supply current is 7.5 mA when active.
Housed in a 4-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm.
The DSC1502AI3A-48M00000 is an active-production part from Microchip. No stock-holding claim is made; sourcing is confirmed per RFQ.
The frequency stability is ±20 ppm over the operating temperature range. This is tight enough for most MCU clocking, USB, and 10/100 Ethernet applications — for precision timing like 1 GbE or wireless base stations, a ±10 ppm or TCXO would be needed.
Yes — it is a drop-in functional replacement for a 48 MHz quartz XO in the same 7.0 x 5.0 mm footprint, provided the supply voltage (2.5V–3.3V) and output type (LVCMOS) match. The MEMS resonator gives better shock and vibration tolerance, and faster start-up, but the electrical interface is identical.
Yes — the supply voltage range is 2.5V to 3.3V, so it runs directly from a 3.3V rail. The LVCMOS output swings rail-to-rail, so it drives 3.3V logic inputs without level translation.
