Clock Generator for Broadcom Processor

8V49N211

DATA SHEET

General Description

Features

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.

• 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

IDT’s Fourth Generation FemtoClock^®NG technology has best in

class phase noise performance.

• Crystal oscillator interface designed for 25MHz (C_L= 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 3.3V operating supply voltage

• Lead-free (RoHS 6) packaging

• -40°C to 85°C ambient operating temperature
