Interface Applications
For Input Interface Applications see Figures 4a through
4e. For CML Output Termination, see Figures 5a
through 5d.
CML Output Termination with 1.2V V
For VCCO of 1.2V, Figure 5a, terminate the output with
50Ω-to-1.2V, DC coupled, not 100Ω differentially across
the outputs.
If AC-coupling is used, Figure 5d, terminate into 50Ω-
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, 50Ω ANY-IN input. AC-coupling will offset the
output voltage by 200mV and this offset voltage will be
too low for proper driver operation. Any unused output
pair needs to be terminated when V
leave floating.

CML Output Termination with 1.8V/2.5V V
For V
with either 50Ω-to-V
outputs. AC- or DC-coupling is fine. See Figure 5c for
AC-coupling.
Input AC-Coupling
The SY56016R input can accept AC-coupling from any
driver with voltage swing between 0.2V to 1.0V (See DC
Electrical Characteristics for more details). Bypass VT
with a 0.1µF 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.
Input Termination
From 1.8V CML driver: Terminate with VT tied to 1.8V.
Do not terminate 100Ω differentially.
From 2.5V CML driver: Terminate with either VT tied to
2.5V or 100Ω differentially.
The input cannot be DC-coupled from a 1.2V CML
driver.
