FEMTOCLOCKS LVDS/LVPECL ZERO DELAY BUFFER/ CLOCK GENERATOR FOR PCI EXPRESS AND ETHERNET ICS8743004I The ICS8743004I is Zero-Delay Buffer/Frequency Multiplier with four differential LVDS or LVPECL HiPerClockS output pairs pin selectable output type , and uses external feedback for “zero delay” clock regeneration. In PCI Express and Ethernet applications, 100MHz and 125MHz are the most commonly used reference clock frequencies and each of the four output pairs can be independently set for either 100MHz or 125MHz. With an output frequency range of 98MHz to 165MHz, the device is also suitable for use in a variety of other applications such as Fibre Channel 106.25MHz and XAUI 156.25MHz . The M-LVDS Input/Output pair is useful in backplane applications when the reference clock can either be local on the same board as the ICS8743004I or remote via a backplane connector. In output mode, an input from a local reference clock applied to the CLK/nCLK input pins is translated to M-LVDS and driven out to the MLVDS/nMLVDS pins. In input mode, the internal M_LVDS driver is placed in Hi-Z state using the OE_MLVDS pin and MLVDS/nMLVDS pin then becomes an input e.g. from a backplane . The ICS8743004I uses very low phase noise FemtoClock technology, thus making it ideal for such applications as PCI Express Generation 1 and 2 as well as for Gigabit Ethernet, Fibre Channel, and 10 Gigabit Ethernet.

FEMTOCLOCKS LVDS/LVPECL ZERO DELAY BUFFER/ CLOCK GENERATOR FOR PCI EXPRESS AND ETHERNET

ICS8743004I

The ICS8743004I is Zero-Delay Buffer/Frequency

Multiplier with four differential LVDS or LVPECL

HiPerClockS output pairs pin selectable output type , and uses
external feedback for “zero delay” clock
regeneration. In PCI Express and Ethernet
applications, 100MHz and 125MHz are the most commonly used
reference clock frequencies and each of the four output pairs can
be independently set for either 100MHz or 125MHz. With an
output frequency range of 98MHz to 165MHz, the device is also
suitable for use in a variety of other applications such as Fibre

Channel 106.25MHz and XAUI 156.25MHz . The M-LVDS

Input/Output pair is useful in backplane applications when the
reference clock can either be local on the same board as the

ICS8743004I or remote via a backplane connector. In output
mode, an input from a local reference clock applied to the

CLK/nCLK input pins is translated to M-LVDS and driven out to the

MLVDS/nMLVDS pins. In input mode, the internal M_LVDS driver
is placed in Hi-Z state using the OE_MLVDS pin and

MLVDS/nMLVDS pin then becomes an input e.g. from a
backplane .

The ICS8743004I uses very low phase noise FemtoClock technology, thus making it ideal for such applications as PCI Express Generation 1 and 2 as well as for Gigabit Ethernet, Fibre Channel, and 10 Gigabit Ethernet. It is packaged in a 40-VFQFN package 6mm x 6mm .
• Four differential output pairs with selectable pin type LVDS or

LVPECL. Each output pair is individually selectable for 100MHz or 125MHz for PCIe and Ethernet applications .
• One differential clock input pair CLK/nCLK can accept the
following differential input levels LVPECL, LVDS, M-LVDS, LVHSTL, HCSL
• One M-LVDS I/O MLVDS/nMLVDS
• Output frequency range 98MHz - 165MHz
• Input frequency range 19.6MHz - 165MHz
• VCO range 490MHz - 660MHz
