The wide supply range of 2.25 V to 3.6 V means the same part works across 2.5 V and 3.3 V rails without a separate LDO.
The 6-SMD no-lead package (2.50 mm × 2.00 mm, 0.90 mm seated height) is a standard MEMS oscillator footprint compatible with reflow soldering.
The DSC1104DE1-125.0000 is a 125 MHz XO (Standard) oscillator with an HCSL output. HCSL is a differential current-steering logic level commonly used for PCIe reference clocks.
Yes, the part includes a standby (power down) function. When the enable pin is pulled low, the oscillator enters standby and draws 95 µA max. Pulling the pin high returns the output to the active 125 MHz clock.
Yes, it is a drop-in replacement for a quartz XO in the same 6-SMD footprint, with the added benefits of MEMS reliability and a standby function. The HCSL output, however, is differential — if the original design used a single-ended CMOS oscillator, the receiver must accept HCSL levels.
