Product details

Dual LVPECL clock from a MEMS resonator

The DSC400-0202Q0106KE1 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two LVPECL output frequencies: 153.6 MHz and 155.46875 MHz. These frequencies align with common 10 GbE and Fibre Channel line rates, making this oscillator a direct fit for a switch or router reference-clock tree. The silicon die is sealed in the 20-VFQFN package, which measures 5.00 mm x 3.20 mm with a 0.90 mm height.

Supply range and output enable

Rated for a 2.25 V to 3.6 V supply, this oscillator runs from a 2.5 V or 3.3 V rail without a separate LDO.

Active sourcing — no obsolescence risk

Microchip lists the DSC400-0202Q0106KE1 as Active.

Frequently asked questions

Is the DSC400-0202Q0106KE1 a crystal or an oscillator?

It is an XO (Standard) — a complete oscillator with a MEMS resonator inside. You do not add external load capacitors or an inverter; just apply power and the two LVPECL outputs run at 153.6 MHz and 155.46875 MHz.

Does the DSC400-0202Q0106KE1 have a pin-compatible alternative in the same family?

The DSC400 series includes many frequency combinations and output logic types (LVDS, HCSL, CMOS). A pin-compatible alternative would need the same 20-VFQFN footprint and supply range but different output frequencies or logic. Confirm the BOM's required frequencies before cross-referencing — the DSC400 base product number covers multiple variants, but the exact frequency pair is order-code specific.
