8413S08集成電路（IC）的時鐘發(fā)生器PLL頻率合成器規(guī)格書PDF中文資料

General Description

The 8413S08 is a high performance PLL-based clock generator

optimized for processor core, PCI/PCI-X/PCIe bus, SGMII and

Gigabit Ethernet PHY clocks. The clock generator offers ultra-low

jitter outputs that make it ideal to serve as a central clocking device

for multiple clock destinations. The output frequencies are generated

from a 25MHz parallel resonant crystal, or external differential input

source. The industrial temperature range of the 8413S08 supports

tele-communication, networking and storage requirements.

Features

? Eight selectable 100MHz or 125MHz clocks for PCI Express? and

sRIO, HCSL interface levels

? One 156.25MHz SGMII clock, LVPECL interface levels

? Three LVCMOS/LVTTL outputs, 20? output impedance

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

source

? Crystal oscillator interface designed for 25MHz, parallel resonant

crystal

? Differential CLK, nCLK input pair that can accept: LVPECL, LVDS,

LVHSTL, HCSL input levels

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

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