DUAL GIGABIT ETHERNET TRANSCEIVER
October 13, 2000 / Revision D
OUTPUT LOAD
The S2068 serial outputs require a resistive load to
set the output current. The recommended resistor
value is 4.5 k
to ground. This value can be varied
to adjust drive current, signal voltage swing, and
power usage on the board.
ACQUISITION TIME
With the input eye diagram shown in Figure 21, the
S2068 will recover data with a
1E-9 BER within the
time specified by T
LOCK
in Table 18 after an instan-
taneous phase shift of the incoming data.
