8V19N880
RF Sampling Clock Generator and Jitter Attenuator
Datasheet
The 8V19N880 is a fully integrated FemtoClock® RF Sampling Clock Generator and Jitter Attenuator. The device is designed as a high-performance clock solution for conditioning and frequency/phase management of wireless base station radio equipment boards. The 8V19N880 is optimized to deliver excellent phase noise performance as required in 4G, 5G, and including mmWave radio implementations. The device supports JESD204B (subclass 0 and 1) and JESD204C.
A two-stage PLL architecture supports both jitter attenuation and frequency multiplication. The first stage PLL is the jitter attenuator and uses an external VCXO for best possible phase noise characteristics.
