Product details

Quad LVPECL clock source for 100/125 MHz reference trees

The 2.25V–3.6V supply range lets it run from a 2.5V or 3.3V rail without a dedicated LDO, and the Enable/Disable function allows the outputs to be tri-stated during system sleep or test modes.

Package, footprint, and temperature grade

Housed in a 20-VFQFN with exposed pad (5.00 mm × 3.20 mm, 0.90 mm height), the part requires a thermal via array under the pad for adequate heat transfer — the exposed pad is the primary thermal path, not the package body.

Frequently asked questions

What are the output frequencies and signal type of the DSC400-2222Q0118KE1T?

All four outputs are LVPECL, each delivering either 100 MHz or 125 MHz — the order code sets all outputs to the same pair of frequencies (–). The ±50 ppm stability keeps the clock edge jitter within the budget for 10 GbE and PCIe Gen 3 reference clocks.

Is the DSC400-2222Q0118KE1T a drop-in replacement for the DSC400-2222Q0118KE0T?

The evidence does not list a DSC400-2222Q0118KE0T or any cross-reference. The DSC400 base product number shares the same 20-VFQFN package and pinout across the series, but confirm the output frequency configuration and supply voltage range against your BOM before substituting.
