MEMS resonator replaces quartz — what that means for the BOM
The DSC1101DI2-025.0000T uses a MEMS resonator rather than a quartz crystal — the base resonator is MEMS, so there is no quartz blank to age or fracture under vibration. Startup is deterministic: the oscillator reaches the rated 25 MHz CMOS output within microseconds of power-up, with no crystal startup delay or load-capacitance tuning. For a BOM line that previously specified a quartz XO, this part drops the external load caps and the startup margin calculation.
Supply range and standby — fitting the rail
The supply range spans 2.25V to 3.6V, so the same oscillator can serve a 2.5V FPGA bank and a 3.3V PHY without a rail-specific variant. When the Standby (Power Down) function is asserted, the supply current drops to 95 µA max — the oscillator stops and the output goes high-impedance, which lets the downstream device enter a low-power sleep state without a clock glitch.
The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a low-profile footprint that fits under a shielding can or on a dense PCB without blocking a via field.
Active status and sourcing posture
Sourced through independent distribution; quoted to order against the BOM quantity. No pin-compatible second source is listed, but the DSC1101 series includes multiple frequency and stability variants that share the same 6-VDFN footprint.
