Quad-output MEMS clock in a 5×3.2 mm QFN
The DSC400-3133Q0080KE1 is a MEMS-based XO (Standard) that delivers four independent frequencies from a single 20-VFQFN package: 148.35 MHz, 27 MHz, 25 MHz, and 148.35 MHz. Outputs are configurable as LVCMOS or LVDS, giving the board designer flexibility to drive single-ended or differential clock lines without a separate translator. Supply voltage spans 2.25 V to 3.6 V, so the same part can run from a 2.5 V or 3.3 V rail — no need to stock multiple voltage variants.
Active production with ±50 ppm stability
Housed in a 20-VFQFN Exposed Pad measuring 5.00 mm × 3.20 mm with a 0.90 mm height — the exposed pad requires a thermal via pattern under the package for proper heatsinking and ground return. Supplied in tube; the MEMS resonator provides faster startup and better shock tolerance than quartz, relevant for portable or vibration-prone installations.
