8V19N850D
Description
The 8V19N850 is a fully integrated Radio Unit Clock Synchronizer and Converter Clock Generator designed as a high-performance clock solution for phase/frequency synchronization and signal conditioning of wireless base station radio equipment. The device supports JESD204B/C subclass 0 and 1 device clocks and SYSREF synchronization for converters.
The 8V19N850 supports two independent frequency domains: one that can be used for the digital clock (Ethernet and FEC rates) domain with four outputs, and the device clock (RF-PLL) domain with 12 outputs. The Ethernet domain generates frequencies from two independent APLLs for flexibility; the outputs of the RF clock domain generate very low phase noise clocks for ADC/DAC circuits.
From the integrated RF-PLL, the device supports the clock generation of high-frequency device clocks for driving ADC/DAC devices low-frequency synchronization signals (SYSREF).
A dual DPLL front-end architecture supports any frequency translation. Each...
