Operates from 2.25V to 3.63V, covering common 2.5V and 3.3V rails without an extra regulator – the Enable/Disable function pulls supply current from 32 mA (active) down to 22 mA (disabled) for power-sensitive sleep modes.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm – the exposed pad aids thermal transfer to the PCB ground plane, important when the oscillator sits near a hot FPGA or ASIC.
Ensures compatibility with the target circuit's power rail.
LVDS vs other outputs determines termination and signal integrity requirements.
Required for regulatory and environmental compliance in many designs.
Physical footprint must match PCB layout and soldering process.
Helps with second sourcing or finding better price/lead time.
Directs to immediate purchase, reducing time-to-delivery.
