100 MHz HCSL MEMS oscillator for PCIe clocking
The 2.25V to 3.6V supply range lets the same oscillator serve 2.5V and 3.3V rails without a separate voltage regulator — a single BOM line covers both power domains in a mixed-voltage design.

Product details
Frequently asked questions
What is the exact output type of the DSC1104BI5-100.0000T?
HCSL (High-Speed Current Steering Logic) — a differential output standard used for PCIe reference clocks and other high-speed serial interfaces.
Does the DSC1104BI5-100.0000T support both 2.5V and 3.3V supplies?
Yes. The supply voltage range is 2.25V to 3.6V, so the same oscillator works on a 2.5V or 3.3V rail without a regulator.
Is the DSC1104BI5-100.0000T a drop-in replacement for standard 6-pin oscillators?
The 6-SMD, no lead package and 5.00mm x 3.20mm footprint match the industry-standard 6-pin oscillator layout. Confirm the pin function order against your existing footprint — the HCSL output may require different termination than a single-ended LVCMOS oscillator.
What is the standby power consumption of the DSC1104BI5-100.0000T?
When the Standby (Power Down) function is active, the maximum supply current is 95 µA. Active current is 42 mA max.
