Semtech Debuts ToPSync(TM) Timing Platform with World's First Integrated IEEE1588 PTP & SETS Synchronization Device

ToPSync Synchronization Platform Improves Quality of Service;
Robust ACS9510 Device Has Three Years of Continuous Performance
Testing
CAMARILLO, Calif.--(Business Wire)--
`Semtech Corp. (Nasdaq:SMTC), a leading supplier of analog and
mixed-signal semiconductors, today announced the ToPSync(TM) (Timing
Over Packet Synchronization) ACS9510 device, the first network
synchronization device that combines IEEE1588v2 Precision Time
Protocol (PTP) with Semtech's market leading SONET/SDH synchronous
equipment timing source (SETS) solution. The ACS9510 device is the
first product in a new platform of timing solutions that meets the
increasing needs of carriers worldwide in 3G, 4G, LTE (Long Term
Evolution) and WiMAX applications.

The ACS9510 enables IP networks to provide time alignment between
base station nodes or network switches. As a consequence, it is no
longer necessary to use costly GPS modules and oscillators at each
node, each of which can cost up to $500. The solution also facilitates
the move from traditional leased lines to the use of public IP
networks to provide the backhaul for broadband wireless base stations.
Some Semtech customers have realized cost savings of up to $50,000 per
year per base station by moving to IP backhaul. ToPSync enables
customers deploying next-generation wireless technologies such as
WiMax, LTE (long-term evolution) and 4G to achieve precise time
alignment down to 1us accuracy.

After extensive trials, several carriers have standardized on the
solution for their IP backhaul networks. These carriers tested
Semtech's Timing over Packet Synchronization technology under heavily
congested network conditions using a suite of tests and found that the
device delivered better than 1us of time alignment. The ACS9510 has
undergone three years of continuous performance testing by a number of
carriers.

"We are very pleased that, based on the stringent trials at
carriers, our technology has been selected for use in WCDMA, GPON,
WiMAX and other products, all due for imminent launch," said Rich
Lansdowne, Product Group Manager at Semtech. "The IEEE 1588v2
technology satisfies a long felt need for carriers to move to IP
backhaul. As the market leader in telecom synchronization solutions,
we are very excited by the opportunities that are emerging in this
market space."

The ACS9510 ToPSync device can operate in a traditional role in
the SONET/SDH network providing a high-precision synchronization
solution within network elements, or it can use the ToPSync platform
technology to provide reference clock signal transport across a
carrier IP network. In its PTP role it can operate as a Grandmaster or
a slave allowing for full hybrid deployment between packet- and
circuit-based networks.

Semtech's ToPSync solution automatically adapts to packet delay
variation, packet jitter and network reconfigurations to maintain the
required frequency accuracy, phase stability or full time alignment.
The ACS9510 IC also incorporates a precision holdover feature to
maintain clock accuracy in the event of a network failure. In
worldwide trials lasting for more than three years, ToPSync has
consistently demonstrated high performance and robustness.

Key Features of the ACS9510

-- Fully integrated - IEEE1588 PTP Grandmaster, PTP Slave and
SONET/SDH clock (TDM Timing) solution. Integrates hardware
precision time stamping with on-the-fly insertion. Powerful
processor and clock recovery algorithm integrated. Backwards
compatibility mode with Semtech ACS8520 SETS.

-- PTP Grandmaster selection - according to Best Master Clock
(BMC) algorithm

-- Powerful network delay analysis delivers full time alignment
in the slave over hostile networks, including Layer 2 & 3
routed.

-- Dynamic adaptation to network delay variations. Network
loading change tolerant.

-- Time alignment performance better than +/-2 us on a managed
5-switch GbE network under G.826120 test conditions.

-- Frequency alignment performance better than +/-10 ppb on a
managed 5-switch GbE network under G.826120 test conditions.

-- Standard compliance - IEEE 1588 v213, G.826120
