Product details

100 MHz MEMS XO with HCSL output

The 42 mA max supply current at 100 MHz is typical for a differential-output MEMS oscillator at this frequency.

Microchip lists the DSC1124BE1-100.0000T as Active.

Temperature grade and stability

This covers indoor and most outdoor telecom/small-cell enclosures; for engine-bay or downhole use, the wider-temperature DSC1124 variants would be needed.

6-SMD no-lead footprint

The 5.00 mm × 3.20 mm × 0.90 mm 6-SMD no-lead package is a standard MEMS oscillator footprint, compatible with many SiTime and other MEMS oscillator pads. The low seated height (0.90 mm) suits tight card-edge or mezzanine spacing.

Frequently asked questions

Is the DSC1124BE1-100.0000T equivalent to the SiT9102?

Both are MEMS oscillators in similar 6-SMD packages, but the DSC1124BE1-100.0000T outputs HCSL, while the SiT9102 typically outputs LVCMOS or LVDS. The output format is not pin-compatible — check the receiver input type before substituting.

What is the output type of the DSC1124BE1-100.0000T?

It is HCSL (High-Speed Current Steering Logic), a differential output standard used for PCIe reference clocks and other high-speed serial interfaces.

Is the DSC1124BE1-100.0000T compatible with a 3.3 V supply?

The Enable/Disable pin is referenced to Vdd.
