The ML4039EML is a fully featured 400G BERT that can be configured as a 4channel PAM4 56 GBaud or 4-channel NRZ 56 Gbps lanes. Also half rates around 28 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 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.
Key Features :
– Data Rates: 23 – 29 & 46 – 58 Gbps
Ability to tune the bit rate in steps of 100 kbps and find the RX PLL locking margin.
Independent control of inner eye levels Up to 1.8 Vpp output swing single-ended Supports Gray coding and polarity inversion
