Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific frequency pair (156.25 MHz and 174.703083 MHz) against design requirements, as dual-frequency variants are distinct from single-frequency models. Confirm the LVPECL output compatibility with downstream logic inputs. Ensure the 7 mm x 5 mm footprint matches the PCB layout. Check for RoHS compliance status if required by environmental regulations. Validate the enable pin configuration matches the system control scheme.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this component when dual-frequency generation is required without external switching complexity. The LVPECL interface offers superior noise immunity compared to single-ended outputs. Consider the 20 PPM stability for applications demanding tight jitter performance. The 3.3 V operation aligns with standard digital logic levels. Evaluate the 7 mm x 5 mm package size against space constraints in dense assemblies.
