Clock IC From Analog Devices Packs 2.8-GHz VCO

The AD9516 debuts as the industry’s first clock IC to combine low phase noise clock generation with 14-channel clock distribution at jitter levels below 1 ps. The device integrates an integer-N synthesizer, two reference inputs, a 2.8-GHz voltage-controlled oscillator (VCO), programmable dividers, and adjustable delay lines. In addition to eliminating several discrete components, the on-chip VCO diminishes risks associated discrete-oscillator failures. There are five versions of the clock, each supporting a specific frequency range. The high-end AD9516-0 includes a VCO operating from 2.6 GHz to 2.95 GHz. The other devices cover lower frequencies, down to the AD9516-4’s VCO range of 1.5 GHz to 1.9 GHz. Each device can also be used with an external VCO. Shared features include six LVPECL outputs and four/eight outputs that are programmable to either LVDS (four outputs) or CMOS (eight outputs) levels. Pricing is $10.75 each/10,000.
