Zarlink Semiconductor introduces the first in a family of voice processing chips aimed at improving voice quality and reducing noise in hands-free communication devices. The ZL38002 product uses an advanced adaptive algorithm that constantly tracks and reduces background noise while preserving high voice quality. Voice signals are transmitted in both directions, allowing natural two-way conversation, even when signal levels are low. The ZL38002 chip utilizes a non-linear process design supporting full-duplex speech with no switched loss of the signal path. The company’s algorithm design operates during double-talk situations when both callers are speaking at the same time. Programmable noise reduction allows the user to adjust the noise cancellation level to meet system requirements without distorting the audio signal. The ZL38002 device is now available in a 36-pin QSOP (quarter small outline package) and 48-pin TQFP (thin quad flat package) chip measuring 7 × 7 mm. Lead-free package options are also available.
