ACS9593 Provides Cost-Effective Time Synchronization for Pico
Basestations, Femtocells and Other Wireless Base Stations
Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and
mixed-signal semiconductors, today announced the expansion of its
ToPSync(TM) product platform with the availability of the ACS9593, an
IEEE1588v2 precision time protocol (PTP) slave device that is a
cost-effective, high-precision time synchronization solution for
deployment in wireless base stations.
The ACS9593 device provides time recovery and delivery to networking
equipment in wireless base stations used in 3G, 4G, WiMAX and Long Term
Evolution (LTE) networks. The highly precise device delivers time
alignment performance better than ±2 μs
and frequency alignment performance better than ±10
ppb when measured on a managed five-switch Gigabit Ethernet network
under G.8261 test conditions. Previously this level of accuracy could
only be achieved through the use of highly accurate and costly
combinations of GPS modules and oscillators.
With the ACS9593, carriers can deploy wireless femtocells and pico base
stations in large office buildings, apartment complexes and on campuses
to improve coverage, and use an IP network to connect them
cost-effectively to a central switch. Before ToPSync(TM) commercial
availability, providing synchronization meant using a GPS-based
solution, which required costly building retrofits to provide line of
sight to the satellite and the use of an expensive oscillator for
periods of GPS service outage.
“Our ToPSync platform takes the 1588v2
protocol and makes it a game changer in wireless backhaul because it
enables brand new markets for wireless carriers,”
said Rich Lansdowne, Product Group Manager at Semtech. “The
ACS9593 makes this especially true for smaller base stations that are
now shaking up the industry.”
Semtech’s ToPSync product platform gives
carriers a cost-effective way to adopt IEEE1588v2 synchronization
solutions and move away from intricate GPS systems that have high
installation costs and require the ability to access GPS satellites.
