Product details

Four fixed clocks in a single MEMS package

Outputs are configurable as HCSL or LVDS — both supported from the same device, which simplifies BOM consolidation when the system uses mixed logic families.

Supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails; no separate regulator needed if the rail is within that window.

Housed in a 20-VFQFN with exposed pad, 5.0 mm x 3.2 mm body, 0.90 mm height — the pad must be soldered to a ground plane for proper thermal and electrical performance. Supplied in Tape & Reel (TR) — compatible with standard pick-and-place and reflow profiles for the VFQFN package.

Frequently asked questions

What is the output type of DSC400-4334Q0022KI2T?

The device outputs HCSL or LVDS — both are supported from the same pins, selectable per output. This covers PCIe reference clocks (HCSL) and long-trace differential signalling (LVDS) from a single part number.
