Circuit Description
Introduction
The driver circuit will force the DOUT output to one of
three states:
1.
DVH (driver high voltage level)
2.
DVL (driver low voltage level)
3.
High Impedance (Hi Z).
Both driver digital control inputs (DHI/DHI*, DRVEN/
DRVEN*) are wide-voltage differential inputs capable of
receiving ECL, TTL, and CMOS signals. Single-ended
operation is achievable by generating the proper
threshold levels for the inverting inputs.
Drive Enable
The drive enable (DRVEN/DRVEN*) inputs control
whether the driver is forcing a voltage or is placed in a
high-impedance state. If DRVEN is more positive than
DRVEN*, the output will force either DVL or DVH,
depending on the driver data inputs. When DRVEN is
more negative than DRVEN*, the output is set to high-
impedance, independent of the driver data inputs.
Driver Data
The driver data inputs (DHI/DHI*) determine whether
the driver output is high or low. If DHI is more positive
than DHI*, the output will force DVH when the driver is
enabled. If DHI is more negative than DHI*, the output
will force DVL when the driver is enabled.
Table 1 summarizes the functionality of the driver enable
and driver data pins.
Table 1. DRVEN and DHI Pin Functionality
Driver Levels
DVH and DVL are high input impedance voltage controlled
inputs that establish the driver logical high and low levels
respectively.
DVLCAP / DVHCAP
These two analog nodes are brought out to better
stabilize the high and low driver levels. Much like placing
decoupling capacitors on the DVL and DVH input pins,
the DVLCAP and DVHCAP pins require a fixed .01
F
chip capacitor (with good high frequency characteristics)
to ground.
A tight layout with minimum etch is
recommended.
Driver Bias
The BIAS pin is an analog current input that establishes
a reference current for the driver and influences the
overall speed and power consumption of the chip. The
BIAS input current may be varied from 1.0 mA to 2.0
mA. Ideally, a current source would supply this current.
However, a resistor to a voltage source, typically VCC, is
acceptable.
The BIAS input structure is shown in Figure 1.
