PRELIMINARY

LOW SKEW, 1-TO-4 DIFFERENTIAL-TO-

LVDS FANOUT BUFFER

ICS854S14I

GENERAL DESCRIPTION

FEATURES

The ICS854S14I is a high speed 1-to-4 Differential-

• Four differential LVDS outputs

ICS

HiPerClockS™

to-LVDS Fanout Buffer and is a member of the

HiPerClockS™ family of high performance clock

• IN, nIN pair can accept the following differential input levels:

LVPECL, LVDS, SSTL

solutions from IDT. The ICS854S14I is optimized

for high speed and very low output skew, making

• 50Ω internal input termination to V_T

• Output frequency: 1.5GHz

it suitable for use in demanding applications such as SONET,

1 Gigabit and 10 Gigabit Ethernet, and Fibre Channel. The

internally terminated differential input and V^REF_AC pin allow

other differential signal families such as LVPECL, LVDS, and

SSTL to be easily interfaced to the input with minimal use of

external components. The device also has output enable pins

which may be useful for system test and debug purposes.

• Output skew: 30ps (typical)

• Part-to-part skew: TBD

• Additive phase jitter, RMS: 0.135ps (typical)

• Propagation delay: 1.1ns (typical)

• 2.5V operating supply

APPLICATIONS:

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

• Processor clock distribution

• Available in both standard (RoHS 5) and lead-free (RoHS 6)

packages

• 622MHz central office clock distribution

• High speed network routing

• Wireless basestations

• Serdes LVPECL output to FPGA LVDS input translator

• Fibre channel clock distribution

• AMC clock driver for ATCA systems

• Gigabit ethernet clock distibution
