THEORY OF OPERATION
The ADN4667 is a quad line driver for low voltage differential
signaling. It takes a single-ended 3 V logic signal and converts
it to a differential current output. The data can then be trans-
mitted for considerable distances, over media such as a twisted pair
cable or PCB backplane, to an LVDS receiver like the ADN4668,
where it develops a voltage across a terminating resistor, RT. This
resistor is chosen to match the characteristic impedance of the
medium, typically around 100 Ω. The differential voltage is
detected by the receiver and converted back into a single-ended
logic signal.
When DIN is high (Logic 1), current flows out of the DOUT+
pin (current source) through RT and back into the DOUT pin
(current sink). At the receiver, this current develops a positive
differential voltage across RT (with respect to the inverting input)
and gives a Logic 1 at the receiver output. When DIN is low,
DOUT+ sinks current and DOUT sources current; a negative differen-
tial voltage across RT gives a Logic 0 at the receiver output.
The output drive current is between ±2.5 mA and ±4.5 mA
(typically ±3.1 mA), developing between ±250 mV and ±450 mV
across a 100 Ω termination resistor. The received voltage is centered
around the receiver offset of 1.2 V. Therefore, the noninverting
receiver input is typically (1.2 V + [310 mV/2]) = 1.355 V, and the
inverting receiver input is (1.2 V [310 mV/2]) = 1.045 V for
Logic 1. For Logic 0, the inverting and noninverting output
voltages are reversed. Note that because the differential voltage
reverses polarity, the peak-to-peak voltage swing across RT is
twice the differential voltage.
Current mode drivers offer considerable advantages over
voltage mode drivers such as RS-422 drivers. The operating
current remains fairly constant with increased switching
frequency, whereas that of voltage mode drivers increase
exponentially in most cases. This is caused by the overlap as
internal gates switch between high and low, which causes
currents to flow from the device power supply to ground.
A current mode device simply reverses a constant current
between its two outputs, with no significant overlap currents.
This is similar to emitter-coupled logic (ECL) and positive
emitter-coupled logic (PECL), but without the high quiescent
current of ECL and PECL.
ENABLE INPUTS
The active high and active low enable inputs deactivate all the
current drivers when in the disabled state. This also powers
down the device and reduces the current consumption from
typically 20 mA to typically 2.2 mA. A truth table for the enable
inputs is shown in Table 5.
