射频同步器和 JESD204B/C 时钟抖动衰减器提供业界领先的相位噪声,以实现最佳 4G/5G 射频 EVM 性能。对于增强型通用公共射频接口 (eCPRI) 和 CPRI 应用来说,其具有出色的近端相位噪声,而对于高密度射频来说,其具有高扇出。

单芯片射频同步器件集成数字锁相环 (DPLL) 和高性能射频锁相环,并支持 PTP (精确计时协议、IEEE 1588)、同步以太网、1PPS 输入和输出信号以及紧密相位对齐。

此类器件几乎消除了输入参考时钟内的所有噪声,使其可用于数据转换器参考时钟的生成和同步。

8V19N880, 8V19N882 Low-Power 4G & 5G RF Clock Jitter Attenuators

The 8V19N880 and 8V19N882 JESD204B/C clock jitter attenuators deliver low phase noise and exceptional jitter performance as low as 74fs RMS and -90dB spurious attenuation for mission-critical industrial data converter applications in wireless radio, test and measurement, instrumentation, and high-performance imaging. They support frequencies up to 3932.16MHz (up to 6GHz with an external VCO) and feature 16 and 18 integrated differential outputs to deliver a first-in-class balance of high performance, low voltage and low power consumption with 1.8V support.
