AD9516-0BCPZ

The AD9516-0BCPZ is a high-performance clock generator and fanout distribution IC from Analog Devices. It integrates a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) tunable from 2.55 GHz to 2.95 GHz, providing precise frequency synthesis for demanding applications. The device accepts a single clock input and delivers up to 14 outputs configurable as LVPECL (up to 1.6 GHz), LVDS (up to 800 MHz), or CMOS (up to 250 MHz). Differential input and output support is included, with an input-to-output ratio of 1:14. Additive output jitter is typically 225 fs rms for LVPECL and 275 fs rms for LVDS, with low output skew of 5 ps typical between LVPECL outputs sharing the same divider.

Operating from a supply voltage of 3.135V to 3.465V, the AD9516-0BCPZ is specified over the industrial temperature range of -40°C to +85°C. The device is housed in a 64-lead LFCSP surface-mount package (9 mm x 9 mm) with an exposed pad for enhanced thermal performance. It includes programmable dividers and coarse phase delays on each output pair, as well as fine delay adjustment on LVDS outputs. Automatic output synchronization on power-up and manual sync capability are built in.

Typical applications include low-jitter clock distribution for 10/40/100 Gb/sec networking line cards, clocking high-speed ADCs, DACs, DDSs, and FPGAs in communications systems, wireless transceiver clock generation, and automated test equipment (ATE). The device supports reference monitoring and automatic revertive or manual reference switchover/holdover modes.
