Enabling Security and Surveillance Systems
In an increasingly connected world, physical threats continue to be a major concern for governments,
industry and consumers alike. With new video processing, motor control and audio processing capabilities,
modern security systems include cameras that need to process a large amount of data and transform it into
information that can help us identify threats and prevent them from becoming reality. Moderns cameras have
IP connectivity, either via wired Ethernet, IEEE802.11 WiFi or HDBaseT, and many need to be deployed in
harsh outdoor scenarios, where energy efficiency is of critical importance.
Microsemi has been supplying products for the analog surveillance market since the mid 1970’s, and to the IP surveillance market
since its inception. Microsemi’s comprehensive complete product portfolio for IP Cameras covers both their implementation and
their deployment into virtually any field situation.

Microsemi AcuEdge
™
Technology
New high-performance audio processors enable the streamlined development of IP cameras and Enterprise hands-free
communication. Microsemi’s voice processing technology integrates industry leading features and dedicated firmware to deliver
high-quality hands-free voice performance while reducing system design complexity.
Microsemi’s AcuEdge™ Technology audio processors
(i.e. ZL38050) enable the streamlined development of IP
cameras for HD Voice capability in 2 way hands-free audio.
Microsemi’s AcuEdge Technology integrates industry
leading features and dedicated firmware to deliver
high-quality hands-free voice performance while reducing
system design complexity.
Hands-Free Advantages
In complex noise environments such as large conference
rooms and building lobbies, Microsemi’s AcuEdge
Technology cancels echo, maintains a constant ambient
noise (comfort noise) and converges during double-talk
situations. While most solutions deliver only half-duplex
operation, Microsemi’s proprietary algorithm is able to
continuously converge and track changes in the echo path
to support full duplex operation.
DVR, NVR or security camera users have difficulty trying
to monitor a large number of video feeds for certain
incidents, crimes or events. By adding audio to the surveil-
lance camera, it will enable security personal at the control
room to make judgement calls on security concerns.
Microsemi AcuEdge Technology will provide audio enhance-
ment to allow more accurate monitoring.
Microsemi Audio Processors complement SoC’s that process
video in IP cameras, by adding enhancement features such as
Beam Forming, Sound Locator, Far field microphone pick up
(up to 20m), Automatic Speech Recognition and Sound
Classification.

Diode Bridges
Every PoE PD device requires Diode Bridges at its input. Diode bridges are used to deal with different cable polarities, with power
coming from either wires 1,2,3,6 or wires 4,5,7,8 in the Ethernet cable, and in 4-pairs implementations, from both.
Microsemi offers reliable regular diode bridges, as well as high efficiency, low footprint dual ideal diode bridges for PoE
applications. Easy to add to a design, Microsemi’s PD70224 Ideal Dual Diode Bridge allows a designer to have the same layout
supporting regular, Schottky and ideal diodes, making it easy to fit into the different PoE Class power budgets without knowing the
exact power consumption of the application.
PD70224 Features:
• Active circuit with low forward-drop to replace
dissipative passive diode bridges
• Self-contained drive circuitry for MOSFETs
• Designed to support IEEE802.3af/at, UPOE and
Power over HDBase-T (PoH)
• Integrated 0.16Ohm N-Channel MOSFETs for
0.32Ohm total path resistance
• “Power present” indicator signals for identifying
4-pair bridge power
• Low leakage, < 12µA during detection
• Wide operating voltage range up to 57V
• -40°C to +85°C ambient
• Available in 40 pin package
• RoHS Compliant
