Interfacing/Termination Schemes
Figure 5 shows the recommended
interface termination scheme for
1.25 Gb/s SFF transceivers to Avago
Gigabit Ethernet SerDes ICs, the
HDMP-1636A/1646A. It assumes that
the 3.3 V power supply is common
to both the fiber optic transmitter
and receiver so that the alternative
Notes:
Use surface-mount components for optimum high-frequency performance.
Use 50  microstrip or stripline for signal paths.
Locate 50  terminations at the inputs of receiving units.
* In order to eliminate required external passive components, agilent has included the equivalent of resistors
** C8 is a recommended bypass capacitor for additional low frequency noise filtering.

C5 and C6 within the module. R5 - R8, C5 and C6 are included as part of the application circuit to accommodate
vendors' modules. the HFBR/HFCT-591XE will operate in both configurations.
The signal detect output on the HFBR-591XE contains an internal 1.8 k  pull up resistor. The output stage on the HFCT-591XE is a PU
pull configuration and therefore does not require an external pull up resistor.

can be implemented.
The transmitter input stage is 50 W
terminated so that the +3.3 kW/+5.1
kW resistors provide bias only. These
termination resistors should be po-
sitioned as close as possible to the
device pin.
