The 20-VFQFN exposed pad package (5.00mm x 3.20mm, 0.90mm height) requires a thermal via pattern under the pad for adequate heat dissipation when the device is operating near the upper temperature limit. Frequency stability of ±50 ppm covers temperature, supply, and aging drift — sufficient for 1 GbE and PCIe Gen1/2 applications. For tighter-precision needs (25 ppm or better), a quartz-based TCXO or the DSC600 series with ±25 ppm option would be required. ## Active Lifecycle and Sourcing Profile The Enable/Disable function allows power savings in multi-clock systems by gating outputs without removing supply voltage. Supplied in Tape & Reel (TR) — standard for automated pick-and-place. The DSC400 series is the base product number; the full suffix encodes the output frequency configuration and stability grade. No direct second-source exists; functional equivalents from SiTime or IDT would require a different pinout and board layout.","metaTitle":"DSC400-1444Q0060KI1T MEMS XO Oscillator – Microchip, Active","metaDescription":"Microchip DSC400-1444Q0060KI1T: Active XO, MEMS base, 100MHz x3 + 25MHz outputs, HCSL/LVCMOS, ±50ppm, -40~85°C, 20-QFN.
