The DSC1033CE1-008.0000T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a fixed 8 MHz CMOS output from a 3.3V supply rail. It replaces a quartz crystal + oscillator circuit in a single 4-SMD, No Lead package measuring 3.20mm x 2.50mm.
This makes the part a strong fit for portable or intermittently-powered equipment where the clock must stop during sleep modes.
Yes — the DSC1033CE1-008.0000T is a MEMS-based XO that directly replaces a quartz oscillator module in the same 3.2x2.5mm 4-SMD footprint, with CMOS output and 3.3V supply. It offers lower current draw (3 mA typ vs typical quartz oscillator 5-15 mA) and faster startup, with no external load capacitors needed.
The Standby (Power Down) function disables the output and internal oscillator, reducing supply current to 1 µA max. This is controlled via the enable pin — when pulled low, the oscillator stops; when released or pulled high, it resumes oscillation. Typical startup time after standby is under 1 ms.
