125 MHz MEMS oscillator for tight timing budgets
The DSC1101CI5-125.0000: A MEMS resonator replaces the quartz crystal, which means no load-capacitance tuning and faster startup — the oscillator is ready within a few milliseconds of power-up, a practical advantage when the processor or FPGA needs a stable clock before the boot loader runs.
Supply voltage flexibility and standby power savings
The 2.25V to 3.6V supply range lets this oscillator run directly off a 2.5V or 3.3V rail without an intermediate LDO — one BOM line covers both voltage domains in a mixed-rail design. Standby (Power Down) function disables the output and drops supply current to 95 µA max, useful for battery-powered equipment that wakes periodically to process data then returns to sleep.
Package footprint and board integration
The 6-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits under a shield can or alongside a dense BGA array. Surface-mount assembly with standard reflow profiles; no special handling beyond normal MSL precautions for a plastic-molded MEMS package.
