As shown in Figure 13, there is an internal charge pump used to drive an external loop filter and external
VCXO. The charge pump current is fixed at 250uA. Figure 14 is a simplified block diagram of the external loop
filter and recommended values.

The 2.488/2.666 Gbps transmit serial output is avaliable on TXOP/N pins. The transmit serial output can be AC
or DC coupled to an optical module or electrical interface. A simplified AC coupling block diagram is shown in
Figure 15.

Some optical modules integrate AC coupled capacitors within the module. If so, the external AC coupled capacitors
are not necessary and can be excluded.
