1.25 GHz clock generator with integrated VCO
The AD9528BCPZ-REEL7 is a clock generator from Analog Devices featuring a PLL with bypass mode and an integrated VCO that supports a maximum output frequency of 1.25 GHz. This part is designed for systems requiring multiple synchronized clock domains from two reference inputs, delivering 14 outputs in HSTL or LVDS format. The 2:14 input-to-output ratio means a single device can distribute a clean clock tree across a baseband board or data converter array, reducing external fanout buffers.
ROHS3 compliance is confirmed, so the part meets current European Union restriction-of-hazardous-substances requirements without exemption declarations.
Input and output signal compatibility
The reference inputs accept CMOS, HSTL, or LVDS levels, giving flexibility to interface with crystal oscillators, TCXOs, or differential clock sources. The outputs are HSTL or LVDS, which are common for driving high-speed ADCs, FPGAs, or SerDes transceivers. The differential input and output capability preserves signal integrity over long board traces.
