Product details

Dual-output MEMS clock generator

Output 1 covers 50, 100, 125, 156.25, and 200 MHz; Output 2 covers 10, 50, 100, 125, and 156.25 MHz — both in HCSL logic levels, common for PCIe reference clocks and high-speed SERDES interfaces.

Package and enable control

Housed in a 14-VFQFN with exposed pad (3.20 mm x 2.50 mm, 0.90 mm height) — the centre pad needs a thermal via to the ground plane for heat sinking; hand-soldering is possible with a hot-air station and a fine-tip iron for the perimeter pads.

Product status is Active — Microchip continues to manufacture and support this part for new designs.

Frequently asked questions

Is DSC2044FE1-H0002 a direct replacement for DSC2044FE1-H0001?

The base product number DSC2044 indicates the same family, but the full suffix (FE1-H0002 vs FE1-H0001) defines the specific frequency combination and stability grade. Compare the output frequency tables in the datasheet for your exact BOM position — the two order codes may not be drop-in interchangeable.

What is the frequency stability of DSC2044FE1-H0002?

±50 ppm across the full -20°C to +70°C operating range.

Is DSC2044FE1-H0002 RoHS compliant?

The part is listed as a standard XO in a 14-VFQFN package; Microchip's DSC2044 series is manufactured RoHS-compliant. Confirm the specific date-code compliance with your order.
