Clock Generator for Cavium Processors

ICS8430S07I

DATA SHEET

General Description

Features

The ICS8430S07I is a PLL-based clock generator

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 clocks, and

• One selectable differential LVPECL output pair for DDR

533/400/667

HiPerClockS™

• Six LVCMOS/ LVTTL outputs, 15Ω 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

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

CN3005/CN3010/CN3020 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

ICS8430S07I supports telecommunication, networking, and storage

requirements.

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

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

• RMS phase jitter @ 125MHz, using a 25MHz crystal

(1.875MHz - 20MHz): 0.78ps (typical), QD output

• Output supply:

LVPECL – 3.3V Core

LVCMOS –Core/Output

3.3V/3.3V

Applications

• Systems using CN30XX MIPS64 Broadband Processors

3.3V/2.5V

• 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

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

• Available in lead-free (RoHS 6) package

• 802.11 a/b/g/n wireless for home data and multi-media distribution

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

• Next-generation PON, VDSL2, and Cable Networks

• High-performance NAS

Pin Assignment

• Audio/Video Storage and Distribution

• Consumer Space Media Server
