Product details

114.285 MHz MEMS XO for high-speed clock trees

That frequency is a common reference for 10GbE, Fibre Channel, and high-speed serial transceivers—if your PLL expects 114.285 MHz, this oscillator provides a clean square-wave clock without an external crystal and its load caps. Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without a local regulator. The 6-VDFN exposed-pad package (7.00mm x 5.00mm) keeps the footprint compact, but the exposed pad needs a thermal via under the centre—skip it and the part runs hotter than the 35mA supply current suggests.

Industrial temperature and ±10 ppm stability

The ±10 ppm absolute pull range (APR) sets the frequency accuracy over temperature, supply, and aging; for a 114.285 MHz clock, that translates to roughly ±1.14 kHz of total frequency error, which is tight enough for most Ethernet and SerDes PLLs. That saves power in battery-backed or intermittently-sleeping systems—like a sensor node that wakes to transmit and sleeps between reads.

Frequently asked questions

What is the standby current of DSC1101AI5-114.2850T?

In Standby (Power Down) mode, the supply current is 95 µA max. The output is disabled and the oscillator core is powered down, drawing only leakage current.
