The DSC6003MA3B-PROG is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a CMOS clock output across a 2 kHz to 80 MHz range with ±20 ppm total frequency stability. Its blank (user-programmable) nature means it ships without a pre-set frequency — you program it to the exact output your BOM requires. The 4-VFLGA package (2.00 mm x 1.60 mm, 0.89 mm seated height) is a compact surface-mount footprint that suits space-constrained ECU and sensor module layouts, though the fine-pitch LGA demands careful solder-paste stencil design and X-ray inspection for voiding.
Supply voltage and programming workflow
The wide supply range of 1.71V to 3.63V lets this oscillator run directly from 1.8V, 2.5V, or 3.3V rails without an external level translator — a single BOM line covers multiple power domains. Because the device is blank (user must program), you need Microchip's programming hardware and software (TimeFlash or the DSC-PROG programmer) to set the output frequency before reflow. Plan for an off-line programming step in your assembly flow; the oscillator cannot generate a clock until configured.
The base product number DSC6003 covers the family; the -PROG suffix specifically identifies the blank-programmable variant. If you need a factory-programmed frequency, order the corresponding fixed-frequency DSC6003 part number instead.
