The DSC6003ML3B-008.1920 is a Microchip MEMS-based oscillator delivering a fixed 8.192 MHz CMOS output from a 1.71 V to 3.63 V supply rail — a single part that covers 1.8 V, 2.5 V, and 3.3 V logic families without a voltage translator.
The 4-VFLGA package (2.00 mm x 1.60 mm, 0.89 mm seated height) is a low-profile land-grid array with a 0.50 mm pitch — the small pads demand a controlled stencil and reflow profile, but the MEMS die inside is more shock-tolerant than a quartz blank during board assembly.
