The differential LVPECL swing drives long PCB traces and noisy backplanes without the common-mode noise coupling that single-ended clocks pick up. Supply voltage spans 2.25 V to 3.6 V, which covers 2.5 V and 3.3 V rails without an external regulator.
The 6-SMD no-lead exposed-pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm.
LVPECL (Low-Voltage Positive Emitter-Coupled Logic). It is a differential output that delivers a 375 MHz clock with fast edge rates and good noise immunity for high-speed serial links or FPGA reference clocks.
Yes. The Enable/Disable pin gates the output. When disabled the supply current drops to 22 mA max, useful for power-saving modes in battery-backed or intermittently powered systems.
