The MAX9425/MAX9427 have internal 50
series-out-
put termination resistors and 8mA internal pulldown
current sources, removing the need for external termi-
nation. The MAX9424/MAX9426 have open-emitter out-
puts, which require external termination (see the
Output
Termination
section).
Enable
Setting EN = high and
EN
= low enables the device.
Alternatively, setting EN = low and
EN
= high forces the
outputs to a differential low; all changes on CLK, SEL,
and IN_ are ignored.
Asynchronous Operation
Setting SEL = high and
SEL
= low enables the four chan-
nels to operate independently. The clock signal is
ignored in this mode. When asynchronous mode is
selected, drive or bias the CLK and
CLK
inputs. Biasing
the clock inputs properly is shown in Figure 5. This pre-
vents the unused clock inputs from toggling, which elimi-
nates unnecessary switching noise.
