8V19N492 NG Jitter Attenuator and Clock Synthesizer

The 8V19N492 is a fully integrated FemtoClock NG jitter attenuator and clock synthesizer designed as a high-performance clock solution for conditioning and frequency/phase management of wireless base station radio equipment boards. The device is optimized to deliver excellent phase noise performance.

8V19N492 Features

* ▪ High-performance clock RF-PLL with support for JESD204B ▪ Optimized for low phase noise: -150dBc/Hz (800kHz offset; 245.76MHz clock) ▪ Integrated phase noise of 80fs RMS typical (12kHz

* 20MHz). ▪ Dual-PLL architecture ▪ 1st-PLL stage with external VCXO for clock jitter attenuation ▪ 2nd-PLL
