The DSC6003HI2B-019.2000 is a 19.2 MHz MEMS-based XO from Microchip's DSC60XXB series, delivering a CMOS output with ±25 ppm frequency stability across the full -40°C to 85°C range.
Supply flexibility and enable/disable control
The 1.71V–3.63V supply range lets the oscillator run directly from a 1.8V, 2.5V, or 3.3V rail without an intermediate LDO — one less part to qualify and place.
Package footprint and layout considerations
Housed in a 4-VFLGA package measuring 1.6 mm x 1.2 mm with a seated height of 0.89 mm, this oscillator fits tight PCB real estate but demands careful solder-paste stencil design for the small land pads — a 0.50 mm pitch or finer stencil aperture is typical. Surface-mount assembly on standard FR-4 is fine; the MEMS die inside is already sealed at the wafer level, so no special moisture sensitivity level handling beyond the standard MSL rating applies.
