The DSC400-1111Q0090KI1T packs four independent LVCMOS clock outputs — 10 MHz, 27 MHz, 148.5 MHz, and 125 MHz — into a single 5.00 mm × 3.20 mm 20-VFQFN package, replacing up to four discrete oscillators on the BOM.
Runs from a 2.25 V to 3.6 V supply rail, so it can share a 2.5 V or 3.3 V rail without an extra regulator — the wide range covers both core and I/O voltages in mixed-logic designs.
Design engineers need the datasheet to validate pin compatibility and electrical parameters before incorporating the part into a design.
Sourcing buyers need to know immediate availability to fill a BOM line without production delays.
Buyers compare pricing across distributors to minimize cost for their project.
Engineers need to confirm the output logic level and voltage compatibility with the rest of the circuit.
Brokers and buyers need lifecycle status to avoid purchasing a part that may become unavailable.
If the part is hard to source or obsolete, maintenance techs and buyers need a compatible substitute.
