With ±50 ppm frequency stability and a 2.25 V to 3.6 V supply range, it replaces four discrete crystal oscillators on the board, saving layout area and reducing BOM line count. The Enable/Disable function lets firmware gate each output independently for power-down modes or test isolation without external muxing. Housed in a 20-VFQFN Exposed Pad package (5.00 mm x 3.20 mm, 0.90 mm height), the exposed pad requires a thermal via array under the package to dissipate heat from the MEMS die and output drivers.","metaTitle":"DSC400-1111Q0091KI1T Microchip MEMS XO Quad LVCMOS","metaDescription":"Active MEMS XO, four outputs (12/24/48/14.25 MHz), LVCMOS, -40 to 85°C, Enable/Disable.

The Enable/Disable function allows each output to be tri-stated independently. This is useful for power-cycling unused clock domains in the system or isolating the oscillator during board-level test without adding external logic."},{"question":"What is the difference between DSC400 and DSC1000 series?","answer":"The DSC400 series integrates four independent MEMS oscillators in a single package, each with its own output frequency. The DSC1000 series is a single-output MEMS oscillator. The DSC400 saves board space and BOM count when a system needs multiple clock frequencies from one device."},{"question":"How can I request pricing and lead time for DSC400-1111Q0091KI1T?","answer":"Submit an RFQ with your target quantity.
