AZ100EP16VS

The AZ10/100EP16VS is a SiliconGermanium (SiGe) differential receiver with variable output swing. The EP16VS has functionality and output transition times similar to the EP16, with an input that controls the amplitude of the Q/Q¯ outputs.

Connecting the BOOST pin to VEE increases the output swing by about 15% above standard ECL/PECL levels.
The BOOST pin is internally tied to VEE for the SOIC 8 and TSSOP 8 packages, and is under external user control for the MLP 16 package. When both the BOOST pin and the VCTRL pin are not connected, the part operates with the
standard ECL/PECL output and VBB levels of the AZ10/100EP16 device. To ensure best performance, the BOOST pin should be tied to VEE when the variable swing feature is used.

The operational range of the EP16VS control input, VCTRL, is from VREF (full swing) to VCC (min. swing).
Maximum swing is achieved by leaving the VCTRL pin open or tied to VEE. Simple control of the output swing can be btained by a variable resistor between the VREF and VCC pins, with the wiper driving VCTRL. Typical application ircuits and results are described in this Data Sheet.

The EP16VS provides a VREF (VBB/VREF) output for a DC bias when AC coupling to the device. The VREF pin should be used only as a bias for the EP16VS as its current sink/source capability is limited. Whenever used, the VREF pin should be bypassed to ground via a 0.01F capacitor.

Under open input conditions for D/D¯, the Q/Q¯ outputs are not guaranteed.

NOTE: Specifications in ECL/PECL tables are valid when thermal equilibrium is established.
