The DSC6003HA3B-016.0000 is a 16 MHz MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a CMOS output from a 1.71V–3.63V supply rail. Its AEC-Q100 qualification places it in the automotive temperature and reliability band — suitable for under-hood and cabin-domain ECUs that need a stable reference without a quartz crystal's startup and shock sensitivity.
Supply range and current budget fit
The 1.71V–3.63V supply range lets this oscillator run directly from a 1.8V, 2.5V, or 3.3V rail — no extra LDO in the clock-tree branch. Typical supply current is 1.3 mA, which keeps the power contribution below 5 mW even at 3.63V. For a battery-backed always-on module, that draw is well inside the sleep-budget margin.
Package and board layout constraints
The 4-VFLGA package measures 1.60 mm x 1.20 mm with a seated height of 0.89 mm. The land-grid array has no exposed leads — the PCB footprint must match the recommended land pattern exactly, and the solder-paste stencil aperture should be sized to avoid bridging under the package body.
No pin-compatible second source is documented in the DSC60XX series; the base product number DSC6003 identifies the family, and the full order code DSC6003HA3B-016.0000 is the specific variant.
