• Manufacturer Part Number: S2062
• Description: Dual Serial Backplane Device
• Manufacturer: AMCC (Applied Micro Circuits Corp)

OUTPUT LOAD
The S2062 serial outputs require a resistive load to
set the output current. The recommended resistor
value is 4.5K
to adjust drive current, signal voltage swing, and
power usage on the board.
ACQUISITION TIME
With the input eye diagram shown in Figure 22, the
S2062 will recover data with a 1E-9 BER within the
time specified by T
taneous phase shift of the incoming data.
