The SK10/100EL16V is a differential receiver with variable output swing. Its VCTRL input controls the amplitude of the Q and Q* outputs. The operating range of the EL16V control input, VCTRL, is from VBB (large swing) to VCC (min swing), see Figure 2. Simple control of the output swing can be obtained by a variable resistor between the VBB and VCC pins, with wiper driving CTRL. Typical application circuits and results are described in Figures 1a, 1b, and 2.
