DATA SHEET
General Description
The ICS8530I-01 is a low skew, 1-to-16 Differential- to-3.3V LVPECL
Fanout Buffer. 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
common mode voltage is within the specified minimum and
maximum 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
• Sixteen differential 3.3V LVPECL output pairs
• CLK, nCLK input pair
• CLK, nCLK pair can accept the following differential input
levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
• Maximum output frequency: 500MHz
• Translates any single-ended input signal to 3.3V LVPECL levels
with a resistor bias on nCLK input
• Output skew: 75ps (maximum)
• Additive phase jitter, RMS @ 106.25MHz: 0.162ps (typical)
• Full 3.3V supply voltage
• -40°C to 85°C ambient operating temperature
• Available in both standard (RoHS 5) and lead-free (RoHS 6)
