Product details

200 MHz LVPECL from a MEMS resonator — what it buys you

The LVPECL output swings rail-to-rail with a typical 800 mVpp differential swing, driving 50-Ω terminated lines directly — no external bias resistors needed. At 200 MHz the 58 mA max supply current is the thermal budget to check: in still air the 6-SMD package dissipates that with minimal rise, but in a 85 °C ambient the junction stays within the silicon rating.

Microchip lists the DSC1122CI5-200.0000T as Active.

Frequently asked questions

Is the DSC1122CI5-200.0000T a drop-in replacement for a standard 200 MHz quartz oscillator?

Pin-compatible with the standard 6-SMD no-lead footprint (3.2 mm × 2.5 mm), but the output is LVPECL, not LVCMOS. A quartz oscillator with LVCMOS output will not drive LVPECL inputs directly — check the receiver's input type. The MEMS base also means faster start-up and better shock tolerance than quartz.

Can the DSC1122CI5-200.0000T run from a 3.3 V supply?

Yes. The supply range is 2.25 V to 3.6 V, so both 2.5 V and 3.3 V rails work. The LVPECL output swing scales with the supply but stays within the receiver's common-mode range as long as the termination matches the supply.
