The 2.488/2.666GHz transmit serial output has a primary and secondary channel. By default, the serial output
stream is multiplexed to both channels. However, the secondary channel can be configured to output the
2.488/2.666GHz serial data stream or the transmit serial clock according to the state of TXO2_SEL. If
TXO2_SEL is pulled "Low", the secondary channel will output the serial data stream. If TXO2_SEL is pulled
"High", the secondary channel will output the transmit serial clock. In addition, the secondary channel can be
disabled by pulling TXO2_DIS "High". If the secondary channel is disabled, the secondary serial output data
will be pulled "High". The transmit serial output should be AC coupled to an optical module or electrical
interface. A simplified block diagram is shown in Figure 13.

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