2.5 Small Form-factor Pluggable (SFP) optical transceivers

This application uses at least three DACs: two for receiver and transmitter power monitors and one for transmitter-mode configuration. The integrated DACs are more easily programmed up to a 12-bit resolution using minimal PCB size, which is especially important in SFP applications. Figure 6 shows an SFP optical transceiver board using three smart analog combo SAC-L3 configurations.
