ML4039EML (f)

The ML4039EML is a full feature 400G BERT that can be configured as a four-channel PAM4 58 GBaud or four-channel NRZ 58 Gbps lanes. Also, half rates around 26 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 of 16384 UI maximum size.

The transmitters are single-ended with swing up to 1800 mVpp to enable driving EML-based optics. The error detectors are differential pairs with adaptive front-end signal conditioning.
