Supply voltage spans 1.8V to 3.3V, letting a single BOM line serve both 1.8V-core and 3.3V-I/O domains — useful when the same oscillator feeds an MCU core clock and a peripheral bus.
Housed in a 4-SMD, no-lead exposed-pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a standard 7x5 mm oscillator footprint that is pin-compatible with many quartz oscillators of the same size.
Yes, in the same 7x5 mm 4-pin footprint, the DSC1001AI2-042.0000T is a drop-in replacement for a 42 MHz quartz oscillator with CMOS output. The MEMS resonator eliminates the need for external load capacitors and is less sensitive to shock and vibration. Confirm that your board's supply voltage (1.8V–3.3V) and stability requirement (±25 ppm) match.
Yes, the standby (power-down) function disables the output and drops supply current to 15 µA max. The oscillator resumes normal operation when the standby pin is de-asserted; no external pull-up or pull-down is required.
