The DSC1001AE2-002.0480 is a MEMS-based XO (Standard) oscillator delivering a 2.048 MHz CMOS output — the standard clock rate for T1/ framing and audio master clocks.
Operates from 1.8V to 3.3V, so the same part number works across a 1.8V MCU core and a 3.3V peripheral bus without a second oscillator variant.
Housed in a 4-SMD, No Lead package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a standard 7x5 mm oscillator footprint that matches many quartz XO land patterns. Surface-mount mounting with no exposed leads means the part sits flush on the PCB; the 0.90mm height keeps it under low-profile enclosures.
