Product details

156.25 MHz MEMS clock for SerDes and Ethernet

The DSC1101AI5-156.2500T is a MEMS-based XO delivering a 156.25 MHz CMOS output — the exact frequency used as a reference clock for 10GbE, PCIe Gen3/4, and many FPGA SerDes PLLs. Supply voltage spans 2.25V to 3.6V, so the oscillator can be powered directly from a 2.5V or 3.3V rail without an intermediate LDO — one less component on the power tree.

Standby mode and low-power operation

Maximum supply current is 95 µA during normal operation, making this oscillator a low-power choice for battery-powered or energy-harvested systems where every microamp counts.

The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

Is DSC1101AI5-156.2500T a MEMS oscillator?

Yes, the base resonator is MEMS, not quartz. This gives better shock/vibration tolerance and faster start-up compared to a conventional crystal oscillator.

Does DSC1101AI5-156.2500T have standby mode?

Yes, the function is Standby (Power Down). When enabled, the output goes to high-impedance and the supply current drops to near-zero.

What is the output type of DSC1101AI5-156.2500T?

The output is CMOS, a single-ended logic level compatible with most digital inputs.
