Four-frequency MEMS clock generator in a 5×3.2 mm QFN
The DSC400-3133Q0080KE1T is a MEMS-based XO (standard) from Microchip's DSC400 series that delivers four independent clock outputs from a single 20-VFQFN package measuring 5.00 mm × 3.20 mm with a 0.90 mm height. Output frequencies are factory-programmed: 148.35 MHz on outputs 1 and 4, 27 MHz on output 2, and 25 MHz on output 3 — each available in LVCMOS or LVDS format, selectable per output pair.
Supply range, stability, and temperature envelope
Operates from a single 2.25 V to 3.6 V supply, covering common 2.5 V and 3.3 V logic rails without an external regulator.
