No stock-holding claim — quoted per order. ## 6-VDFN package — board layout note Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits under low-profile enclosures or alongside dense BGA clusters. No via-in-pad needed unless routing density forces it.","metaTitle":"DSC1121DM2-016.6400 MEMS Oscillator 16.64 MHz CMOS -55°C to","metaDescription":"Microchip DSC1121DM2-016.6400 XO (Standard) 16.64 MHz CMOS output, ±25 ppm stability, -55°C to 125°C, 6-VDFN package.

The MEMS resonator provides better shock and vibration immunity than quartz, and the -55°C to 125°C range exceeds most quartz parts. Confirm the Enable/Disable logic polarity matches your circuit."},{"question":"Does the DSC1121DM2-016.6400 support a 3.3 V supply?","answer":"Yes — the supply range is 2.25 V to 3.6 V, so 3.3 V is within spec. The same part also runs on 2.5 V rails without a separate regulator."},{"question":"What is the frequency stability of the DSC1121DM2-016.6400?","answer":"±25 ppm over the full -55°C to 125°C range.
