ICS8530I-01
LOW SKEW, 1-TO-16
DIFFERENTIAL-TO-3.3V LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
ICS
The ICS8530I-01 is a low skew, 1-to-16 Differ-
ential-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 ICS8530I-01 ideal for those clock distribution applications
demanding well defined performance and repeatability.
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: 500MHz
• Translates any single-ended input signal to
3.3V LVPECL levels with a resistor bias on nCLK input
• Output skew: 50ps (typical)
• Part-to-part skew: 100ps (typical)
• Additive phase jitter, RMS @ 106.25MHz:
0.022ps (typical) @ 25°C
• 3.3V output operating supply
• -40°C to 85°C ambient operating temperature
