What this clock generator does for your clock tree
The AD9516-1BCPZ-REEL7 is a clock generator and fanout distribution IC from Analog Devices, integrating a PLL to synthesize and distribute up to 14 clock outputs from a single input. It supports CMOS, LVDS, and LVPECL output formats, letting you drive mixed-logic clock trees without external level translators. Its 2.95 GHz maximum frequency targets high-speed ADC/DAC clocking, FPGA reference clocks, and RF LO distribution where jitter and skew matter. The 1:14 fanout ratio reduces the number of clock buffers and splitters on the board, simplifying layout and saving space.
Why the 2.95 GHz ceiling matters for your design
At 2.95 GHz, this part covers L-band and lower C-band applications, including cellular base station local oscillators, radar IF sampling clocks, and high-speed data converter clocking. The PLL with integrated VCO means you get a complete synthesis loop in one package — no external VCO or loop-filter design needed. The differential input and output capability preserves signal integrity over long PCB traces and through connectors, critical when routing clocks across a multi-card backplane or to remote ADC banks.
It is ROHS3 compliant, meeting current environmental regulations for solder reflow and end-product compliance.
Package and supply rail checklist
Surface-mount 64-VFQFN exposed pad, also specified as 64-LFCSP-VQ (9x9). The 3.135V to 3.465V supply range is a tight 3.3V nominal ±5% — a clean 3.3V rail with low ripple is essential for PLL phase-noise performance. Plan for dedicated LDO or filter on the supply input.
