Product details

Quad-output MEMS oscillator with LVDS signalling

Output bank 1 provides 25MHz, 50MHz, 125MHz, and 150MHz; output bank 2 provides 100MHz and 156.25MHz – a fixed frequency set that suits multi-rate Ethernet, FPGA reference clocks, or base station timing where multiple synchronous rails are needed. The MEMS resonator eliminates quartz start-up variability and shock sensitivity, making this oscillator a drop-in replacement for standard crystal oscillators in designs that already accept LVDS levels.

The 2.25V to 3.6V supply range means the same part runs on a 2.5V or 3.3V rail without a separate level translator – the LVDS output common-mode voltage tracks the supply, so the receiving FPGA or SerDes input sees a valid differential swing across the full range.

Enable/disable function and package footprint

The 20-VFQFN with exposed pad (5.00mm x 3.20mm, 0.90mm height) requires a thermal pad on the PCB for heat sinking; the 0.50mm pitch pads demand careful fan-out but keep the footprint smaller than a comparable 14-pin SOIC oscillator bank.

Frequently asked questions

How can I order the DSC400-3333Q0001KI1T and check availability?

The DSC400-3333Q0001KI1T is an active Microchip part supplied on tape and reel. We source through independent distribution and quote to order against your BOM quantity. Submit an RFQ for current pricing and lead time – no stock-holding claim is made here.

What is the exact frequency combination of the DSC400-3333Q0001KI1T?

Output bank 1 delivers 25MHz, 50MHz, 125MHz, and 150MHz; output bank 2 delivers 100MHz and 156.25MHz – six frequencies total across four LVDS outputs.

Can the DSC400-3333Q0001KI1T replace a standard quartz crystal oscillator?

Yes, it is a drop-in replacement for standard XOs in designs that accept LVDS levels. The MEMS resonator offers faster start-up and better shock resistance than quartz, but the pinout and supply voltage (2.25V–3.6V) must match the existing footprint.

What does the enable/disable pin do on this oscillator?

The enable/disable pin gates all LVDS outputs without removing the supply. When pulled low, the outputs enter a high-impedance state (tristate), which is useful for power sequencing or test isolation.

Is the DSC400-3333Q0001KI1T compatible with 3.3V logic?

Yes – the supply range is 2.25V to 3.6V, so it runs directly on a 3.3V rail. The LVDS output common-mode voltage tracks the supply, ensuring compatibility with 3.3V LVDS receivers.
