ZL38002 Features
• 112 ms acoustic echo canceller
• Up to 12 dB of noise reduction
• Works with low cost voice codec. ITU-T G.711 or signed mag /A-Law, or linear 2's compliment
• Each port may operate independently in companded format or linear 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
• Programmable offset nulling of all PCM channels
• Serial micro-controller interface
• Idle channel noise suppression
• ST-BUS, GCI, or variable-rate SSI PCM interfaces
• User gain control provided for speaker path (-24 dB to +21 dB in 3 dB steps)
• Adjustable gain pads from -24 dB to +21 dB at Xin, Sin and Sout to compensate for different system requirements
• AGC on speaker path
• Handles up to -6 dB acoustic echo return loss (with the appropriate gain pad settings)
• Transparent data transfer and mute options
• 20 MHz master clock operation
• Low power mode during PCM Bypass
• Bootloadable for future factory software upgrades
• 2.7 V to 3.6 V supply voltage; 5 V-tolerant inputs
