Adjustable De-Emphasis
ISL35111 features a settable de-emphasis driver for custom
signal restoration.
The connectivity of the DE pins are used to determine the boost
de-emphasis level of ISL35111. Table 1 defines the mapping
from the 2-bit non-binary DE word to the 7 available output
de-emphasis levels.
Disable Pin
The disable (TDSBL) pin is used to disable the driver output in
order to implement TX_Disable functions of such industry
standards as SFP+ and QSFP. When this pin is pulled HIGH, the
ISL35111 will enter a low-power standby mode. For active data
transmission, this pin must be pulled LOW.
Line Silence/Quiescent Mode
The ISL35111 is capable of maintaining periods of line silence by
monitoring its input pins for loss of signal (LOS) conditions and
subsequently muting the output driver when such a condition is
detected. A reference voltage applied to the detection threshold
(DT) pin is used to set the LOS threshold of the internal signal
detection circuitry. For most applications, it is recommended to
leave the DT pin floating at its default internal bias. If the
sensitivity of the detection threshold needs to be adjusted, the DT
voltage can be adjusted with an external pull-up resistor. The
resistor values should be validated on an application-specific
basis. Connect the DT pin to ground in order to disable this
feature and prevent the outputs from muting during line silence.
