Product details

Frequency stability is rated at ±10 ppm, which holds the timing budget for most 1000BASE-T and PCIe Gen1/2 reference clocks without needing a temperature-compensated oscillator.

Supply range and power budget for the BOM

The 6-VDFN package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a compact footprint that fits tight board areas, but the exposed pad and fine-pitch terminations require a well-planned solder-paste stencil and via pattern for thermal and electrical connection.

It is not qualified for industrial or outdoor use where ambient temperatures exceed +70°C or drop below -20°C.

Frequently asked questions

Can DSC1121BE5-098.3040 run on a 2.5 V supply?

Yes. The supply voltage range is 2.25 V to 3.6 V, so a 2.5 V rail is within specification. No external regulator is needed if the rail is stable within that window.
