3.9 Serial Digital Output
The GS9062 contains an integrated current mode differential serial digital cable
driver.
To enable this output, SDO_EN/DIS must be set HIGH by the application layer.
Setting the SDO_EN/DIS signal LOW will cause the SDO and SDO output pins to
become high impedance, resulting in reduced device power consumption.
With suitable external return loss matching circuitry, the GS9062's serial digital
outputs will provide a minimum output return loss of -15dB at 270Mb/s.
The integrated cable driver uses a separate power supply of +1.8V DC supplied via
the CD_VDD and CD_GND pins.
3.9.1 Output Swing
Nominally, the voltage swing of the serial digital output is 800mVp-p single-ended
into a 75
Ω
load. This is set externally by connecting the RSET pin to CD_VDD
through 281
Ω .
The output swing may be decreased by increasing the value of the RSET resistor.
The relationship is approximated by the curve shown in
Figure 3-4
.
Alternatively, the serial digital output swing can drive 800mVp-p into a 50
Ω
load.
Since the output swing is reduced by a factor of approximately one third when the
smaller load is used, the RSET resistor must be 187
Ω
to obtain 800mVp-p.

3.9.2 Serial Digital Output Mute
The GS9062 will automatically mute the serial digital output when the LOCKED
output signal is LOW. In this case, the SDO and SDO signals are set to a constant
voltage level.
