AD9516-5提供多路输出时钟分配功能，具有亚皮秒级抖动性能，并且片内集成锁相环(PLL)，可以配合外部VCO/VCXO使用。
The AD9516-5 has excellent low jitter and phase noise characteristics that greatly improve data converter performance and are suitable for other applications where phase noise and jitter are critical.
The AD9516-5 has six LVPECL outputs in three groups and four LVDS outputs in two groups. Any LVDS output can be reconfigured to two CMOS outputs. The LVPECL output operates at 1.6 GHz, the LVDS output at 800 MHz, and the CMOS output at 250 MHz. Each pair of outputs has a crossover that can be set for both the crossover ratio and coarse delay (or phase). LVPECL outputs are available in a crossover range of 1 to 32. The crossover range of LVDS/CMOS outputs is up to 1024.
The AD9516-5 is available in a 64-pin LFCSP package and can be operated from a single 3.3 V supply, which requires a wider voltage range when using an external VCO, which can be achieved by connecting a charge pump supply (VCP) to a 5.5 V voltage. The stand-alone LVPECL power supply can be from 2.375 V to 3.6 V. The AD9516-5 is rated for an operating temperature range of −40°C to +85°C standard industrial temperature range.
For applications that require integrated EEPROM or require more output, the AD9520-5 and AD9522-5 are available.
