What this clock generator does in a high-speed system
The AD9518-0ABCPZ from Analog Devices is a clock generator with integrated PLL and six LVPECL fanout outputs, accepting CMOS, LVDS, or LVPECL reference inputs. It synthesizes and distributes clean clock signals up to 2.95 GHz, making it a fit for ADC/DAC clocking, FPGA reference clock trees, and RF/data-converter front-ends in communications infrastructure, test equipment, and radar systems. The 1:6 input-to-output ratio with all-differential signal paths keeps jitter low and edge rates controlled across the industrial temperature range of -40°C to 85°C.
Lifecycle and supply position
ADI lists the AD9518-0ABCPZ as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so the part is qualified for ongoing production and new designs. For dual-sourcing or a slightly lower frequency alternative, the AD9518-4ABCPZ (1.8 GHz) shares the same package and pinout — verify the output divider settings match your application.
