Interface Applications
For Input Interface Applications, see Figures 4a
through 4f and for CML Output Termination, see
Figure 5a through Figure 5d.
CML Output Termination with VCCO 1.2V
For VCCO of 1.2V, Figure 5a, terminate the output
with 50-to-1.2V, DC coupled, not 100 differentially
across the outputs.
If AC-coupling is used, Figure 5d, terminate into 50-
to-1.2V before the coupling capacitor and then
connect to a high value resistor to a reference
voltage.
Do not AC couple with internally terminated receiver.
For example, 50 ANY-IN input. AC-coupling will
offset the output voltage by 200mV and this offset
voltage will be too low for proper driver operation.
CML Output Termination with VCCO 1.8V
For VCCO of 1.8V, Figure 5a and Figure 5b,
terminate with either 50-to-1.8V or 100
differentially across the outputs. AC- or DC-coupling
is fine.
Input AC Coupling
The SY54017AR input can accept AC-coupling from
any driver. Bypass VT with a 0.1F low ESR capacitor
to VCC as shown in Figures 4c and 4d. VT has an
internal high impedance resistor divider as shown in
Figure 2a, to provide a bias voltage for AC-coupling.
