ML4079ELN PCIe BERT
- Series: BERT - Brand: Te-lead
Introduction
The ML4079ELN is a fully featured 800G BERT that can be configured for eight channels of 1-1.5Gbps; 2.55-5.9Gbps; 7.3-11Gbps; 24-32Gbps and 41-66Gbps NRZ and 21.25-21.75GBaud; 26.5625-36GBaud and 44-66GBaud PAM4.
The transmitters support all standard test patterns mandated by IEEE802.3ck stress testing and OIF such as PRBS13Q, PRBS31Q, etc. Tx can also be programed to output a user-defined pattern.
The ML4079ELN supports transmitter and receiver equalization up to 34dB to overcome signal integrity impairments due to channel losses or reflections.
Additionally, users can opt to programmatically add an ISI channel equivalent to a frequency-dependent attenuator with 1 to 9dB loss at Nyquist.
The ML4079ELN is specifically for linear optic, PCIe Gen 3.0, 5.0 , 6.0 and 7.0, and Active and Passive Cable with high Rx equalization capabilities.
