AZ10/100EP16VS
ECL/PECL Differential Receiver
with Variable Output Swing
ENGINEERING NOTES
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 MSOP8 package, and is under external user control for the MLP16 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 AZ10/100EP16VS 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
obtained by a variable resistor between the VREF and VCC pins, with the wiper driving VCTRL. Typical application circuits
and results are shown in Figures below.
The AZ10/100EP16VS 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 AZ10/100EP16VS as its current sink/source capability is limited. Whenever used, the
VREF pin should be bypassed to ground via a 0.01µF 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.
