MC100EP16VT: Differential Driver / Receiver with Variable Output Swing and Internal Input Termination

The MC100EP16VT is a differential receiver functionally equivalent to the 100EP16 with input pins controlling the amplitude of the outputs (pin 1) and providing an internal termination network (pin 4).The VCTRL input pin controls the output amplitude of the EP16VT and is referenced to VCC. The operational range of the VCTRL input is from ≤ VBB (a supply at VCC -1.42 V, maximum output amplitude) to VCC (minimum output amplitude). VBB is an externally supplied voltage equal to VCC -1.42 V. A variable resistor between VCC and VBB, 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 VTT input pin offers an internal termination network for a 50 line impedance environment. For further reference, see Application Note AND8020, Termination of ECL Logic Devices. Input considerations are required for D and Dbar under no signal conditions to prevent instability.Special considerations are required for differential inputs under No Signal conditions to prevent instability.
