Operating from 2.25V to 3.6V, this oscillator spans 2.5V and 3.3V rails without a dedicated LDO — a single supply rail serves both the oscillator and the downstream FPGA or MCU bank.
Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the part fits tight PCB stacks in automotive camera modules or telematics units.
This qualifies it for under-hood and cabin electronic modules where reliability against thermal and mechanical stress is required.
The output is CMOS at 125 MHz, suitable for driving digital loads such as FPGA clock inputs, MCU oscillators, or Ethernet PHY reference clocks directly. The Enable/Disable function lets the output be tri-stated for power management.
