8V49N211 - Clock Generator

General Description

The 8V49N211 is a high-performance PLL-based clock generator designed to interface with Broadcom XLP2xxx processors.

The 8V49N211 has one 25MHz crystal input to generate output frequencies to support XLP Core/DDR3, USB, SGMII/XAUI and PCIe reference clocks in a single chip.

Key Features

  • Fourth Generation FemtoClock® NG PLL technology.
  • Two LVCMOS clock outputs for core/DDR3 at 133.33MHz or 66.66MHz.
  • One LVDS clock output for USB at 100MHz.
  • Three LVDS clock outputs for SGMII/XAUI at 125MHz.
  • Five HCSL clock outputs for PCIe at 100MHz.
  • Crystal oscillator interface designed for 25MHz (CL = 12pF) frequency, IDT Part #603-25-173.
  • PCI Express Gen 1 (2.5Gb/s), Gen 2 (5Gb/s) and Gen 3 (8Gb/s) jitter compliant.
  • Full.
