Serial System Interface
The serial interface permits the LXT6155 to communicate with an Overhead Termination device at
155.52 Mbps. Data and clock lines are differential 3.3V LVPECL signals. Refer to Figure 11.
2.7
Parallel System Interface
Parallel interface allows the LXT6155 to communicate with the system chip at 19.44 MHz, 8 bits
per clock cycle. Data and clock lines are TTL compatible signals. Refer to Figure 12.
