It accepts a single clock input and distributes it across 14 differential outputs, each independently configurable as CML, LVDS, or LVPECL. The 3.2 GHz maximum output frequency covers the clock rates needed for 10G+ line rates and wideband ADC/DAC sampling. The integrated sweep function allows controlled frequency ramps for FMCW radar and test equipment, eliminating the need for an external DDS or modulation source. ## 3.2 GHz and 1:14 fanout — sizing the clock distribution The 3.2 GHz maximum frequency sets the upper bound for the clock tree. If your ADC or DAC requires a sample clock above 3.2 GHz, this part cannot drive it directly — you would need a higher-frequency PLL or a multiplier stage. Below that ceiling, the 1:14 input-to-output ratio means a single HMC7043LP7FE can replace a PLL plus a separate fanout buffer, saving board area and reducing additive jitter from cascaded devices. The 14 outputs are all differential, so each pair drives a single-ended or differential load depending on the output standard selected. ## Temperature grade and environment Rated for -40°C to 85°C operating temperature, this part is suited for outdoor telecom cabinets, base station equipment, and industrial instrumentation where ambient temperatures can swing. It is not qualified for automotive under-hood environments (no AEC-Q100 listing), but it fits the industrial and communications infrastructure segment well. The ROHS3 compliance means no exemptions for lead in solder — verify your assembly house's reflow profile for the 48-LFCSP package.","metaTitle":"HMC7043LP7FE PLL Clock Generator, 3.2 GHz, 48-LFCSP","metaDescription":"Analog Devices HMC7043LP7FE fractional-N PLL with sweep, 3.2 GHz max, 1:14 fanout, CML/LVDS/LVPECL outputs, -40 to 85°C, 48-LFCSP.
