Clock Generator for Broadcom Processor
8V49N211
DATA SHEET
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. The 8V49N211 low jitter VCO
easily meets PCI Express Gen 1, 2 and 3 requirements.
IDT’s Fourth Generation FemtoClock® NG technology has best in
class phase noise performance.
Features

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
