ICS8535-01

The ICS8535-01 is a low skew, high performance

1-to-4 LVCMOS-to-3.3V LVPECL fanout buffer

and a member of the HiPerClockS™ family of High

Performance Clock Solutions from ICS. The

ICS8535-01 has two single ended clock inputs.

the single ended clock input accepts LVCMOS or LVTTL in-

put levels and translate them to 3.3V LVPECL levels. The

clock enable is internally synchronized to eliminate runt clock

pulses on the output during asynchronous assertion/

deassertion of the clock enable pin.

Guaranteed output and part-to-part skew characteristics

make the ICS8535-01 ideal for those applications demand-

ing well defined performance and repeatability.

• 4 differential 3.3V LVPECL outputs

• Selectable CLK0 or CLK1 inputs for redundant

and multiple frequency fanout applications

• CLK0 or CLK1 can accept the following differential input

levels: LVCMOS or LVTTL

• Maximum output frequency up to 266MHz

• Translates LVCMOS and LVTTL levels to 3.3V

LVPECL levels

• Output skew: 30ps (maximum)

• Part-to-part skew: 150ps (maximum)

• Propagation delay: 1.9ns (maximum)

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
