PLL clock generator with 2.4 GHz output ceiling
The AD9522-5BCPZ is a PLL-based clock generator and fanout distribution IC from Analog Devices, capable of synthesizing and distributing clocks up to 2.4 GHz. That frequency ceiling makes it a fit for high-speed ADC/DAC sample clocks, FPGA reference clocks, and RF LO generation in base station or instrumentation backplanes. It accepts CMOS, LVDS, or LVPECL references and can output the same signal types, with a programmable divider/multiplier on the PLL path. The part supports a 2:12 or 2:24 input-to-output ratio, meaning two reference inputs can feed up to 24 output channels through internal distribution buffers.
Industrial temperature grade and supply rail
The 64-LFCSP-VQ (9x9 mm) package has an exposed pad for thermal dissipation. The pad should be soldered to a copper plane to keep junction temperature within the industrial range.
