TO HELP THE PUSH toward ever-smaller solutions, a clock IC now brings the voltage-controlled oscillator (VCO) on chip. In addition, the AD9516 series integrates an integer-N synthesizer, two reference inputs, programmable dividers, adjustable delay lines, and 14 clock drivers. Compared with existing solutions, this solution enables designers to reduce clocking board space and bill-of-materials (BOM) costs by more than 50 percent. Impressively, the AD9516 series combines low-phase-noise clock generation with 14-channel clock distribution at jitter levels below 1 ps. The IC also promises to diminish the risks associated with the failure of discrete oscillators. The AD9516 has five versions. Each one supports a specific frequency range. The AD9516-0 includes a VCO that tunes from 2.60 to 2.95 GHz. The other parts cover lower frequencies down to the AD9516-4's VCO range of 1.50 to 1.90 GHz. P&A: $10.75 each in 10,000-piece quantities.
