AD9516-4*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)和电压控制振荡器(VCO)。片内VCO的调谐频率范围为1.45 GHz至1.80 GHz。也可以使用最高2.4 GHz的外部VCO/VCXO。
The AD9516-4's excellent low jitter and phase noise characteristics greatly improve data converter performance and are beneficial for other applications with critical phase noise and jitter.
The AD9516-4 provides 6 LVPECL outputs (in three pairs), 4 LVDS outputs in two pairs, and 8 CMOS outputs (two for each LVDS output). 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 AD9516-4 is available in a 64-pin LFCSP package and can be operated from a single 3.3 V supply. When connecting a charge pump power supply (VCP) to a 5V voltage, an external VCO can be used, which requires a wider voltage range. The stand-alone LVPECL supply can be from 2.5 V to 3.3 V (nominal).
The AD9516-4 is rated for an operating temperature range of −40°C to +85°C industrial temperatures.
