8 MHz MEMS XO with Standby — commercial indoor timing
The DSC1033AC1-008.0000T is a MEMS-based oscillator (not quartz) delivering a 8 MHz CMOS output at 3.3 V with ±50 ppm frequency stability. It belongs to Microchip's PureSilicon™ DSC1033 series, intended for general-purpose clocking in commercial equipment (0°C to 70°C).
Microchip lists the DSC1033AC1-008.0000T as Active.
Surface-mount footprint and supply considerations
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Supply current is 3 mA typical during oscillation. The 3.3 V rail must be within ±10 % for the ±50 ppm stability to hold across temperature; a clean local decoupling capacitor (100 nF) at the supply pin is assumed in the datasheet's test conditions.
