The DSC1001AI1-005.0000 is a 5 MHz MEMS-based XO from Microchip's DSC1001 series, delivering a CMOS output over a 1.8V to 3.3V supply range.
Standby mode and supply voltage flexibility
The 6.3 mA max active current at 5 MHz is low enough that the oscillator's thermal contribution to the board is negligible. The 1.8V to 3.3V supply range covers 1.8V, 2.5V, and 3.3V logic rails without an external level translator — the same BOM entry works across different voltage domains by tying the supply pin to the appropriate rail.
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The package is reworkable with standard hot-air equipment; the 0.90mm height means the hot-air nozzle can get close without disturbing adjacent components. The four pads are on a 2.54mm pitch, which is easy to inspect and touch up under a microscope.
Sourced through independent distribution on a quoted-to-order basis. The part is not a stock-holding line; each order is placed against the confirmed supply.
