It outputs a 12 MHz CMOS-level clock — the 3.3V rail drives the output swing directly, so it connects to most digital logic inputs without level translation. The CMOS output is rail-to-rail, which gives clean edges into typical 10–15 pF load capacitances on a PCB trace. ## ±25 ppm stability and commercial temperature range For a 12 MHz clock, this translates to a maximum frequency deviation of ±300 Hz — tight enough for UART baud-rate generation at 115200 bps without cumulative framing errors. ## Standby function and low-power disable Normal operation draws 10 mA max from the 3.3V rail. This makes it usable in battery-powered designs where the clock can be gated off during sleep — the MEMS oscillator starts up faster than a quartz crystal, typically under 5 ms, so the system can wake and clock within a single microcontroller boot sequence. ## 4-SMD no-lead package — board layout note Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The four pads are on the bottom — no leads to inspect after reflow. The small footprint suits space-constrained designs, but the lack of visible solder joints means X-ray inspection is the only way to confirm wetting. Standard reflow profile for lead-free assembly applies.","metaTitle":"DSC1033DC2-012.0000 Obsolete MEMS Oscillator – Microchip","metaDescription":"DSC1033DC2-012.0000 is an obsolete Microchip MEMS XO, 12 MHz, CMOS output, ±25 ppm, 3.3V, 0°C–70°C.

The DSC1033 series is discontinued. For a functionally similar MEMS oscillator at 12 MHz with CMOS output and 3.3V supply, consider the current DSC1001 or DSC1121 series from Microchip — but verify pin compatibility and package dimensions before substituting, as the DSC1033 used a 4-SMD no-lead package that may differ from newer series."},{"question":"Does DSC1033DC2-012.0000 have a CMOS output?","answer":"Yes, the output type is CMOS.
