CLOCK GENERATOR FOR CAVIUM PROCESSORS

ICS840S06I

General Description

Features

The ICS840S06I is a PLL-based clock generator

• Six LVCMOS/ LVTTL outputs, 20Ω typical output impedance

- One selectable core clock for the processor

- One selectable clock for the PCI/ PCI-X bus

- One 125MHz clock reference for GbE MAC

- Three 25MHz clock references for GbE PHY

specifically designed for Cavium Networks SoC

processors. This high performance device is

optimized to generate the processor core reference

clock, the DDR reference clocks, the PCI/PCI-X bus

HiPerClockS™

• Selectable external crystal or differential (single-ended) input

clocks, and the clocks for both the Gigabit Ethernet MAC and PHY.

The clock generator offers ultra low-jitter, low-skew clock outputs,

and edge rates that easily meet the input requirements for the

OCTEON processors. The output frequencies are generated from

a 25MHz external input source or an external 25MHz parallel

resonant crystal. The extended temperature range of the

ICS840S06I supports telecommunication, networking, and

storage requirements.

source

• Crystal oscillator interface designed for 25MHz, parallel

resonant crystal

• Differential input pair (CLK, nCLK) accepts LVPECL, LVDS,

LVHSTL, SSTL, HCSL input levels

• Internal resistor bias on nCLK pin allows the user to drive CLK

input with external single-ended (LVCMOS/ LVTTL) input levels

• Full 3.3V or mixed 3.3V core/2.5V output supply mode

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

• Available in lead-free (RoHS 6) packages

Applications

• Systems using OCTEON MIPS64 Broadband Processors

• Networking, control and storage equipment, including routers,

switches, application-aware gateways, triple-play gateways,

WLAN and 3G/4G access and aggregation devices, storage

arrays, storage networking equipment, servers, and intelligent

NICs

• 802.11 a/b/g/n wireless for home data and multimedia

Pin Assignment

distribution

• QoS for high quality Voice, Video, and Data service

• Next-generationPON, VDSL2, and Cable networks

• High-performance NAS

• Audio/Video Storage and distribution

• Consumer space media server
