The termination resistor (R
T
) value should be equal to the
characteristic
impedance
impedance traces should be used for the outputs and the
termination resistors should be placed near the GS9028.
The inductor (L) and resistor (R) are used to optimize the
output return loss and are PCB dependent. Typically, R
equals the transmission line characteristic impedance and
L is approximately 8.2nH.
of

cable.
Controlled
OUTPUT AMPLITUDE ADJUSTMENT
The GS9028 outputs are adjustable from as low as 50mV to
as high as 1000mV. The output amplitude is set by the R
SET
resistor connected to pin 4. The relationship between the
output amplitude (V
OUT
) and R
SET
is approximately given by
the equation below:
R
SET
= (1.3696 x Z
O
)/(2 x V
OUT
) - 5.5
where Z
O
is in ohms and V
OUT
is in volts.
The minimum value of R
SET
is 46
. For 75
cable and
800mV output amplitudes, the value of R
SET
is 59
. Also,
note that the above formula assumes that the transmission
line is properly end terminated.
