OUTPUT LOAD
The S2060 serial outputs require a resistive load to
set the output current. The recommended resistor
value is 150
adjust drive current, signal voltage swing, and power
usage on the board.
ACQUISITION TIME
With the input eye diagram shown in Figure 19, the
S2060 will recover data with a 10E-9 BER within the
time specified by T
neous phase shift of the incoming data.
