Product details

Obsolete — sourcing through independent channels

The DSC6121CI2A-00AP: Available through independent surplus and broker inventory. Each reel or tube is lot-tracked and verified against the original datasheet parametrics before quoting. Sourced per RFQ; no factory lead time applies.

Package, footprint, and handling

Supplied in tube. The CMOS output swings rail-to-rail into a 15pF load, so no termination resistor is needed for traces under 50mm on a typical 4-layer PCB. The MEMS resonator itself is immune to the vibration-induced phase noise that plagues crystal-based oscillators in fan-tray or motor-drive environments.

Frequently asked questions

What are the two output frequencies of this oscillator?

The DSC6121CI2A-00AP generates a 19.44MHz and a 25MHz clock simultaneously on separate CMOS outputs. Both frequencies are fixed at the factory; no programming or external resistor selection is involved.

What supply voltage range does the DSC6121CI2A-00AP accept?

The 3mA typical supply current is nearly flat across the full voltage range.

How do I source the DSC6121CI2A-00AP now that it is obsolete?

Through independent surplus channels. We verify each lot against the original Microchip specifications — frequency stability, output swing, and supply current — before quoting. Availability and pricing confirmed at RFQ.
