The ICS8501 is a low skew, 1-to-16 Differential Current
Mode Fanout Buffer. The ICS8501 is designed to translate
any differential signal levels to small swing differential
current mode (DCM) output levels. An external reference
resistor is used to set the value of the current supplied to
an external load load/termination resistor. The load
resistor value is chosen to equal the value of the
characteristic line impedance of 50Ω. The ICS8501 is
characterized at an operating supply voltage of 3.3V.
The small swing outputs, accurate crossover voltage and
duty cycle makes the ICS8501 ideal for interfacing to today’s
most advanced microprocessors.
