Product details

125 MHz LVPECL MEMS oscillator for high-speed clock trees

The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails — no separate regulator needed when the oscillator shares a 3.3V plane with the FPGA or ASIC it clocks.

The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts without requiring via-in-pad for the centre pad.

Frequently asked questions

Where can I buy DSC1122CI2-125.0000T and what is its lifecycle status?

We source it through independent distribution; submit an RFQ for current availability and pricing against your BOM quantity.

Is DSC1122CI2-125.0000T suitable for a 3.3V supply?

Yes. The supply range is 2.25V to 3.6V, so a 3.3V rail is well within the operating envelope — no external regulator or level shifter is needed.

Does DSC1122CI2-125.0000T have an enable/disable function?

Yes, the oscillator includes an Enable/Disable pin. When disabled, the maximum supply current drops to 22 mA, allowing the clock to be gated for power savings.

Can I replace a quartz oscillator with DSC1122CI2-125.0000T?

The DSC1122CI2-125.0000T uses a MEMS resonator instead of quartz. It is a drop-in replacement for standard 125 MHz LVPECL oscillators in the same 3.2 mm x 2.5 mm 6-SMD footprint, provided the supply voltage and enable logic are compatible.
