ICS8537-01

HEX, LOW SKEW, 1-TO-2

DIFFERENTIAL-TO-3.3V/2.5V LVPECL CLOCK BUFFER

GENERAL DESCRIPTION

FEATURES

The ICS8537-01 is a Hex low skew, high performance 1-to-2 • Twelve LVPECL outputs

Differential-to-3.3V/2.5 LVPECL Clock Buffer. The ICS8537-

• Selectable differential CLKx, nCLKx inputs

01 has six selectable clock inputs. The CLKx, nCLKx pairs

can accept most differential input levels and translate them to

3.3V or 2.5V LVPECL output levels.Guaranteed output and

part-to-part skew specifications make the ICS8537-01 ideal

for those applications demanding well defined performance

and repeatability.

• CLKx, nCLKx pair can accept the following differential

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

• Maximum output frequency: 700MHz

• Translates any differential input signal (LVHSTL, SSTL,

DCM) to LVPECL levels without external bias networks

• Translates any single-ended input signal to LVPECL

with resistor bias on nCLKx input

• Output skew: 130ps (maximum)

• Bank skew: 20ps (maximum)

• Part-to-part skew: 350ps (maximum)

• Propagation delay: 1.5ns (maximum)

• 3.3V or 2.5V operating supply

• 0°C to 85°C ambient operating temperature

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

(RoHS 6) packages
