FemtoClock® NG Jitter Attenuator and Clock Synthesizer 8V19N490B Datasheet Description The 8V19N490B 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 as required in GSM, WCDMA, LTE, and LTE-A radio board implementations. The device supports JESD204B subclass 0 and 1 clocks. 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.
