AD9517-0
1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2.55 GHz至2.95 GHz。也可以使用高达2.4 GHz的外部VCO/VCXO。
The AD9517-0 has excellent low jitter and phase noise characteristics that greatly improve data converter performance and are also beneficial for other applications where phase noise and jitter are critical.
The AD9517-0 has four LVPECL outputs in two pairs and four LVDS outputs in two pairs. Each 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 AD9517-0 is available in a 48-pin LFCSP package and can be powered 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 AD9517-0 is rated for an operating temperature range of −40°C to +85°C industrial temperatures.
