Product details

100 MHz MEMS clock for PCIe reference designs

The DSC1104DE5-100.0000T is a 100 MHz MEMS-based XO (Standard) from Microchip's DSC1104 series, delivering an HCSL output — the logic level required by PCIe Gen1 through Gen4 root complexes and switches, as well as 100GbE MAC/PHY reference clocks. Its ±10 ppm absolute pull range (APR) covers spread-spectrum modulation and fine frequency tuning; the 2.25V to 3.6V supply range lets it run from either a 2.5V or 3.3V rail without a separate regulator. Maximum supply current is 42 mA.

Package, footprint, and temperature grade

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max. The small footprint suits space-constrained PCIe add-in cards, SFP+ modules, and compact switch designs.

Microchip continues to manufacture the DSC1104 series.

Frequently asked questions

What is the exact frequency of the DSC1104DE5-100.0000T?

100 MHz.

What is the output logic type for the DSC1104DE5-100.0000T?

HCSL (High-Speed Current Steering Logic), the standard clock format for PCIe interfaces.

Is the DSC1104DE5-100.0000T lead-free and RoHS compliant?

The evidence does not explicitly state RoHS compliance, but the DSC1104 series is manufactured by Microchip, which typically produces RoHS-compliant devices. Confirm with the datasheet or your Microchip representative.

What is the frequency stability of the DSC1104 series?

The evidence lists an absolute pull range (APR) of ±10 ppm for this variant. Frequency stability without pulling is not separately stated; the APR figure is the relevant spec for spread-spectrum or VCXO-like tuning.
