Data Sheet

Zarlink has introduced a new generation family of AEC ZL38002 and ZL38004 . Zarlink recommends these products for new designs.
• Contains two echo cancellers 112 ms acoustic echo canceller + 16 ms line echo canceller
• Works with low cost voice codec. ITU-T G.711 or signed mag µ/A-Law, or linear 2’s comp
• Each port may operate in different format
• Advanced NLP design - full duplex speech with no switched loss on audio paths
• Fast re-convergence time tracks changing echo environment quickly
• Adaptation algorithm converges even during Double-Talk
• Designed for exceptional performance in high background noise environments
• Provides protection against narrow-band signal divergence
• Howling prevention stops uncontrolled oscillation in high loop gain conditions
• Offset nulling of all PCM channels
