CLOCK GENERATOR FOR CAVIUM PROCESSORS

ICS840S06I

The ICS840S06I is a PLL-based clock generator
specifically designed for Cavium Networks SoC

HiPerClockS 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 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.
• Six LVCMOS/ LVTTL outputs, 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
• 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
• 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
• 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
