The AZ10/100LVEL16VS is a
differential receiver with variable output swing. The LVEL16VS has functionality and output transition times
similar to the EL16, with an input that controls the amplitude of the Q/Q¯ outputs.
The operational range of the LVEL16VS control input, VCTRL, is from VBB (full swing) to VCC (min. swing).
Maximum swing is achieved by leaving the VCTRL pin open or by tying it to the negative supply (VEE). Simple
control of the output swing can be obtained by a variable resistor between the VBB and VCC pins, with the wiper
driving VCTRL. Typical application circuits and results are described in this Data Sheet.
The LVEL16VS provides a VBB output for single-ended use or a DC bias reference for AC coupling to the
device. For single-ended input applications, the VBB reference should be connected to one side of the D/D¯
differential input pair. The input signal is then fed to the other D/D¯ input. The VBB pin can support 1.5mA
sink/source current. When used, the VBB pin should be bypassed to ground via a 0.01μF capacitor.
Under open input conditions internal input clamps will force the Q output LOW.
NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.
