Transmit Serial Output Control
The 622.08 Mbps STS-12/STM-4 or 155.52 Mbps STS-3/STM-1 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 block diagram with internally AC-coupled SFP is shown in Figure 15. Also, refer to application note
TAN-9132.)
NOTE: Some optical modules integrate AC coupling capacitors within the module. AC or DC coupling is largely specific to
system design and optical module of choice.
