The DSC1001BL1-048.0000 is a MEMS-based XO from Microchip's DSC1001 series, delivering a 48 MHz CMOS clock with ±50 ppm frequency stability across a 1.8V to 3.3V supply range.
Supply voltage and output compatibility
The 1.8V–3.3V supply range covers the common digital rails used in automotive MCUs and SoCs — no external level translator needed when feeding a 3.3V or 1.8V clock input. CMOS output is a standard logic-level clock that interfaces directly with most microcontrollers, FPGAs, and PHYs without AC coupling or termination resistors.
Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator fits the common 5x3.2 mm MEMS oscillator footprint — a drop-in replacement for many SiTime and Microchip DSC1001-series parts. Surface-mount assembly with no exposed pad simplifies layout; the four terminals are supply, ground, output, and enable (standby).
