48 MHz MEMS oscillator – active, standby-capable, ±25 ppm
The DSC1033CE2-048.0000T is a 48 MHz MEMS-based XO (standard) from Microchip's PureSilicon™ series, delivering a CMOS output with ±25 ppm frequency stability across -20°C to +70°C. It draws 4 mA typical in active mode and drops to 1 µA when the standby (power-down) function is asserted – a useful margin for battery-operated or intermittent-duty systems where the clock can be gated between operations.
Package and footprint – 3.2 mm × 2.5 mm 4-SMD
Housed in a 4-SMD, no-lead package measuring 0.126" × 0.098" (3.20 mm × 2.50 mm) with a seated height of 0.035" (0.90 mm). The compact footprint suits space-constrained PCBs in portable or densely populated designs. Surface-mount assembly; the 0.90 mm height allows it to fit under low-profile enclosures or behind display assemblies.
