General 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.

Key Features

  • High-performance radio clock synchronizer clock.
  • Device clock domain (RF-PLL) with support for JESD204B/C.
  • Digital clock domain (Ethernet, FEC) with support for eEEC and T-BC/T-TSC Class C.
  • 2 differential clock reference inputs.
  • 1PPS (1Hz) to 1GHz input frequency.
  • Dual DPLL front-end with independent clock paths.
  • External control of the DCO for IEEE1588.
  • Digital holdover with a 1.1 × 10-7 ppb accuracy.
  • Programmable DPLL loop b.
