The ML4039EN is a full feature 400G BERT that can be configured as a four-channel PAM4 58 GBaud or four-channel NRZ 28/58 Gbps lanes. Also, half rates of 23 to 29 GBd are supported.
The transmitters support all standard test patterns mandated by IEEE and OIF such as PRBS13Q, SSPRQ, PRBS31Q, etc. It is also possible to program the TX to output a user-defined pattern up to 32 kb long.
The ML4039EN is specifically designed to add crosstalk with configurable frequency up to 30 Gbd and amplitude up to 1500 mV to the PPG’s output.
