Timberwolf Digital Signal Processor family,
powered by AcuEdge™ Technology
Designed for Connected Home applications
ZL38060
Preliminary Data Sheet
Description
The ZL38060 is part of Microsemi’s new Timberwolf
audio processor family of products that feature the
company’s innovative AcuEdge acoustic technology,
which is a set of highly-complex and integrated
algorithms. These algorithms are incorporated into a
powerful DSP platform that allow the user to extract
intelligible information from the audio environment.
The Microsemi AcuEdge Technology ZL38060 device
is designed for applications of the connected home. Its
license-free, royalty-free intelligent audio Firmware
(ZLS38060) provides Acoustic Echo Cancellation
(AEC), Noise Reduction (NR) and a variety of other
voice enhancements to improve both the intelligibility
and subjective quality of voice in harsh acoustic
environments.
Microsemi offers additional tools to speed up the
product development cycle. The MiTuner™ ZLS38508
or ZLS38508LITE GUI software packages allow a
user to interactively configure the ZL38060 device.
The optional MiTuner ZLE38470BADA Automatic
Tuning Kit provides automatic tuning and easy control
for manual fine tuning adjustments.

• Boots from SPI or Flash
• Can run unattended (controllerless), self-
booting into a configured operational state
• Flash firmware can be updated from SPI Slave
• Crystal-less operation (with a valid TDM clock)
• 14 General Purpose Input/Output (GPIO) pins
• 2 low power modes controlled by reset
Performance
• AEC Tail Length: 256 ms
• AEC sampling rate: 8 kHz or 16 kHz
• Single-Talk Weighted Terminal Coupling Loss
(TCLw): > 60 dB
• Double-Talk TCLw: > 40 dB
• Double-Talk Attenuation: > 3 dB
• Noise reduction up to 30 dB
The MiTuner™ Automatic Tuning Kit and
ZLS38508 MiTuner GUI
Microsemi's Automatic Tuning Kit option includes:
• Audio Interface Box hardware
• Microphone and Speaker
• ZLS38508 MiTuner GUI software
