The DSC1104DL5-040.0000 is a 40 MHz MEMS-based XO delivering an HCSL differential output — the same signal standard used in PCIe reference clocks and high-speed SerDes. Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator.
The 6-SMD, No Lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight channel spacing on multi-lane clock trees.
Yes — the standby (power down) function is built in. When the enable pin is de-asserted, the output is disabled and the supply current drops to 95 µA max. The HCSL output is high-impedance in standby, so it does not load the clock bus.
Functionally yes — it is a drop-in XO replacement for a 40 MHz HCSL clock. The MEMS resonator is more shock and vibration tolerant than quartz, and the 2.50 mm x 2.00 mm package is smaller than many legacy quartz footprints. Verify the pinout and enable logic against your existing quartz oscillator before committing the BOM.
