MEMS oscillator avoids quartz start-up delays
The DSC1101BI5-016.0000 uses a MEMS resonator instead of a quartz crystal — the MEMS structure starts oscillating in microseconds, not milliseconds, so the MCU clock is stable before the power rail finishes ramping.
Wide supply rail simplifies power tree
The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without a separate LDO — one oscillator serves either rail, reducing BOM line count and board area. Maximum supply current is 35 mA during active operation; in standby (power-down) mode the disable current drops to 95 µA max, letting the system cut clock power during sleep without a load switch.
6-VDFN package and reflow considerations
The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the low profile fits under shielding cans or in tight enclosures, but the exposed pad requires a thermal via pattern for proper solder-joint reliability. Surface-mount assembly: the 6-VDFN is a standard leadless package compatible with lead-free reflow profiles. Check the MSL rating on the reel label before the bake decision — a high-MSL part that skips the pre-bake can popcorn during reflow.
This oscillator is available for both new designs and production replenishment through independent distribution, quoted to order against the BOM quantity. The DSC1101 series includes multiple frequency and stability variants; the DSC1101BI5-016.0000 is the 16 MHz, ±10 ppm, industrial-temperature member. No direct pin-compatible second source is listed, but the DSC1101 family shares the same 6-VDFN footprint and supply range.
