AD9516-3BCPZ

The AD9516-3BCPZ is a high-performance clock generator and fanout distribution IC from Analog Devices. It integrates a low-noise phase-locked loop (PLL) with an on-chip voltage-controlled oscillator (VCO) that tunes from 1.75 GHz to 2.25 GHz. The device also supports an external VCO or VCXO up to 2.4 GHz for flexible frequency synthesis.

The IC provides 14 outputs: six LVPECL output pairs capable of up to 1.6 GHz, four LVDS output pairs up to 800 MHz (each can be reconfigured as two CMOS outputs up to 250 MHz), and additional CMOS outputs. Additive output jitter is 225 fs rms for LVPECL and 275 fs rms for LVDS, with channel-to-channel skew less than 10 ps. The device includes automatic synchronization on power-up and manual output synchronization.

Designed for low jitter and low phase noise clock distribution, the AD9516-3BCPZ is suitable for networking line cards (10/40/100 Gb/sec), SONET, Synchronous Ethernet, OTU2/3/4, forward error correction, clocking high-speed ADCs/DACs, wireless transceivers, and ATE equipment. It operates from a 3.135 V to 3.465 V supply and over a -40°C to +85°C temperature range. The part is housed in a 64-lead LFCSP (9x9 mm) package with exposed pad for thermal management.
