S2067 AMCC (Applied Micro Circuits Corp), S2067 Datasheet - Page 26

• Manufacturer Part Number: S2067
• Description: Dual Serial Backplane Device With Dual I/o
• Manufacturer: AMCC (Applied Micro Circuits Corp)

OUTPUT LOAD
The S2067 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
S2067 will recover data with a 1E-9 BER within the
time specified by T
taneous phase shift of the incoming data.
