Supply voltage and power-down for mixed-rail designs
Supply voltage spans 1.8V to 3.3V, so the same oscillator can feed a 1.8V FPGA bank, a 2.5V SerDes, or a 3.3V MCU without an external LDO — one BOM line covers multiple rail domains. Active current is 7.2 mA max at 27 MHz, which is typical for a MEMS oscillator at this frequency and keeps the thermal contribution in the 5.0×3.2 mm package manageable.
Package and footprint for production assembly
Housed in a 4-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the DSC1001BI1-027.0000 uses a standard 4-pad land pattern that matches many quartz XO footprints — a direct drop-in replacement for existing 5.0×3.2 mm oscillators.
