SK100EL16V

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. SK10/100EL16V application circuits and results are described in Figures 1a, 1b, and 2.

The SK10/100EL16V provides a VBB output for either single-ended use or as a DC bias for AC coupling to the device. The VBB pin of SK10/100EL16V should be used only as a bias for the EL16V as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to VCC via a 0.01 F capacitor.

Under open input conditions, the pulldown resistor on D, pulldown and pullup resistors on D* will force the Q output LOW and Q* output HIGH. The VCTRL pin of SK10/100EL16V should be bypassed to VCC via a 0.01 F capacitor when the pin is used.
