The ML4039EN is a fully featured 400G BERT that can be configured as a 4-channel PAM4 56 GBaud or 4-channel NRZ 28/56 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…
The user may also 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. On top of that, the user can select to programmatically add an ISI channel equivalent to a frequency-dependent attenuator with 1 to 9 dB loss at Nyquist.
When used in conjunction with the ML407PAM clock synthesizer, the ML4039EN can modulate its output pattern with SJ of over 5UI and up to 4 MHz.
