ZL38003 AEC with Noise Reduction & Codecs for Digital Hands-Free Communication
| Product Status - Production |
|
Zarlink has introduced a new generation family of Voice Processors (ZL38004 and ZL38005). Zarlink recommends these products for new designs.
A full Design Manual is available to qualified customers. To register, please send an email to VoiceProcessing@Zarlink.com.
The ZL38003 is an Acoustic Echo Canceller (AEC) with dual codec. The ZL38003 provides 127 ms of acoustic echo cancellation, which makes it ideal for hand free car kits, and speaker phones designs. Each of the codecs in the dual codec can be connected to 1 of 4 four analog ports through a cross point switch. Also, the network side can be routed to a digital PCM interface that input/outputs either linear 2's complement or A-/mu law commanded PCM data.
Features
- Handles up to -6 dB acoustic echo return loss
- 127 ms acoustic echo canceller
- Provides up to 12 dB of Noise Reduction
- Operate in two modes, Dual Analog mode and single Analog mode (other port is digital PCM)
- PCM Data Formats in single Port mode- 16-bit Linear, companded ITU-T A-law or U-law
- Advanced NLP design - full duplex speech with no switched loss on audio paths
- Tracks changing echo environment quickly
- Adaptation algorithm converges even during Double-Talk
- Howling prevention eliminates uncontrolled oscillation in high loop gain conditions
- Two 16 bit linear ACD and DAC that meet ITU-T G.711/712 recommendations
Typical Applications
-
Hands-free car kits
- Full duplex speaker-phone for digital telephone
- Echo cancellation for video conferences
- Intercom Systems
- Security Systems
