Product details

MEMS-based 25 MHz LVPECL clock source

The LVPECL output delivers the fast edge rates and low jitter needed for high-speed clock distribution to FPGAs, SERDES, or Gigabit Ethernet PHYs. Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate LDO.

Housed in a 6-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.50 mm pitch and no-lead construction mean the PCB footprint should match the recommended land pattern — no through-hole rework.

Frequently asked questions

Can DSC1122BE2-025.0000 replace a quartz oscillator on my board?

Yes — the MEMS resonator is a drop-in replacement for quartz in most applications. The DSC1122BE2-025.0000 is pin-compatible with standard 6-pin XO footprints (enable/disable on pin 1, output on pin 4). MEMS oscillators typically offer better shock and vibration tolerance than quartz, and the ±25 ppm stability is comparable to a basic quartz XO.

Is DSC1122BE2-025.0000 compatible with 3.3V systems?

Yes — the supply voltage range of 2.25V to 3.6V covers both 2.5V and 3.3V rails directly. The LVPECL output levels are referenced to the supply voltage, so at 3.3V Vdd the output swing is compatible with 3.3V LVPECL logic.
