LOW SKEW, 1-TO-5, DIFFERENTIAL/

LVCMOS-TO-0.7V HCSL FANOUT BUFFER

ICS85105I

GENERAL DESCRIPTION

FEATURES

The ICS85105I is a low skew, high performance 1-

• Five 0.7V differential HCSL outputs

ICS

HiPerClockS™

to-5 Differential-to-0.7V HCSL Fanout Buffer and

• Selectable differential CLK0, nCLK0 or LVCMOS inputs

a member of the HiPerClockS™ family of High

Performance Clock Solutions from IDT. The

ICS85105I has two selectable clock inputs. The

• CLK0, nCLK0 pair can accept the following differential

input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL

CLK0, nCLK0 pair can accept most standard differential

input levels. The single-ended CLK1 can accept LVCMOS or

LVTTL input levels. The clock enable is internally synchronized

to eliminate runt clock pulses on the outputs during asynchro-

nous assertion/deassertion of the clock enable pin.

• CLK1 can accept the following input levels:

LVCMOS or LVTTL

• Maximum output frequency: 500MHz

• Translates any single-ended input signal to 3.3V

HCSL levels with resistor bias on nCLK input

Guaranteed output and part-to-part skew characteristics make

the ICS85105I ideal for those applications demanding well

defined performance and repeatability.

• Output skew: 100ps (maximum)

• Part-to-part skew: 600ps (maximum)

• Propagation delay: 3.2ns (maximuml)

• Additive phase jitter, RMS: 0.24ps (typical)

• 3.3V operating supply

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

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