LOW SKEW, 1-TO-16
DIFFERENTIAL-TO-3.3V LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS8530-01 is a low skew, 1-to-16 Differen-
,&6
tial-to-3.3V LVPECL Fanout Buffer and a mem-
HiPerClockS™ _{ber of the HiPerClockS™ family of High Perfor-}
mance Clock Solutions from ICS. The CLK, nCLK
pair can accept most standard differential input
levels. The high gain differential amplifier accepts peak-to-
peak input voltages as small as 150mV as long as the com-
mon mode voltage is within the specified minimum and maxi-
mum range.
Guaranteed output and part-to-part skew characteristics
make the ICS8530-01 ideal for those clock distribution appli-
cations demanding well defined performance and repeatabil-
ity.
FEATURES
• 16 differential 3.3V LVPECL outputs
• CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential input
levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
• Maximum output frequency up to 500MHz
• Translates any single-ended input signal to 3.3V LVPECL
levels with a resistor bias on nCLK input
• Output skew: 75ps (maximum)
• Part-to-part skew: 250ps (maximum)
• 3.3V output operating supply
• 0°C to 70°C ambient operating temperature
• Industrial temperature information available upon request
