The MC100EP16VS is a differential receiver with variable output amplitude. The device is functionally equivalent to the 100EP16 with an input pin that controls the amplitude of the outputs. The VCTRL input pin controls the output amplitude of the EP16VS and is referenced to VCC. (See Figure 4.) The operational range of the VCTRL input is from VBB (max output amplitude) to VCC (min output amplitude). (See Figure 3.) A variable resistor between the VCC and VBB pins, with the wiper driving VCTRL, can control the output amplitude. Typical application circuits and a VCTRL Voltage vs. Output Amplitude graph are described in this data sheet. When left open, the VCTRL pin will be internally pulled down to VEE and operate as a standard EP16, with 100% output amplitude. The VBB pin, an internally generated voltage supply, is available to this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. VBB may also rebias AC coupled inputs. When used, decouple VBB and VCC via a 0.01 mF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VBB should be left open.
