For a 100 MHz carrier, that translates to a maximum drift of ±5 kHz — tight enough for most Ethernet, USB, and general-purpose processor clocks without external trimming. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V rails directly. No extra LDO needed if your board already runs one of those voltages. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm footprint, 0.90 mm height).","metaTitle":"DSC400-0414Q0033KE1 MEMS XO – 100/50/125 MHz, HCSL/LVCMOS","metaDescription":"Microchip DSC400-0414Q0033KE1 MEMS XO: 100/50/125 MHz outputs, HCSL/LVCMOS, ±50 ppm stability, 2.25-3.6 V supply, -20°C to +70°C.

This is useful for power sequencing or test modes."},{"question":"What is the closest pin-compatible alternative in the DSC400 family?","answer":"The DSC400 family includes many pre-programmed frequency combinations. A different order code within the same DSC400 series will share the same 20-VFQFN footprint and supply range but with a different output frequency set.
