Product details

Four 125 MHz LVDS lanes from one MEMS resonator

Each output runs at the same frequency — useful for clocking multiple FPGA banks, SerDes lanes, or Ethernet PHYs from one reference without splitting a single-ended signal. Supply voltage spans 2.25V to 3.6V, so it sits on a 2.5V or 3.3V rail without an extra LDO.

20-VFQFN footprint and board layout notes

The 20-VFQFN Exposed Pad package measures 5.00 mm x 3.20 mm with a 0.90 mm height.

Frequently asked questions

Does the DSC400-3333Q0078KE2T have a pin-compatible replacement or second source?

No pin-compatible replacement or official second source is listed in the Microchip documentation. The BOM depends on this specific order code. If a cross-reference is needed, the DSC400 family includes other frequency and stability variants, but each carries a unique ordering code.
