8V19N408
Description
8V19N408 is a fully integrated Femto Clock® NG Jitter Attenuator and Clock Synthesizer. The device is a high-performance clock solution for conditioning and frequency/phase management of wireless base station radio equipment boards and is optimized to deliver excellent phase noise performance. The device supports JESD204B subclass 0 and 1 clock implementations. The device is very flexible in programming of the output frequency and phase. 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.The second stage PLL lock on the VCXO-PLL output signal and synthesizes the target frequency. For flexibility, the second-stage PLL can use one of two VCOs at 2400MHz
- 2500MHz (VCO-0) and 2920MHz
- 3000MHz (VCO-1).
The device supports the clock generation of high-frequency clocks from the selected VCO and low-frequency system...
