SAN JOSE, Calif. -- (Business Wire)
Integrated Device Technology, Inc. (IDT®)
(NASDAQ:IDTI) today introduced a family of IEEE 1588 time and frequency
generator chips to reduce costs while meeting the synchronization needs
of LTE-Advanced, wireless backhaul and heterogeneous networks. The
unique architecture and capabilities of these devices are fully
documented and accessible to allow IEEE 1588 software designers to
implement their own clock recovery algorithms and add value for their
customers through customization and quick turnaround support.
The new
family of chips includes synchronization management devices (SMDs)
and port synchronizers for IEEE 1588 and synchronous Ethernet (SyncE).
The SMDs manage IEEE 1588 time and frequency generation and SyncE
synchronization. The port synchronizers select between redundant SMD
signals and provide accurate time and low-jitter clocks to the network
ports in the system.
The IDT 82P33810,
82P33814
and 82P33831
SMDs reduce the cost of IEEE 1588 clocks by replacing stable but
expensive oven-controlled crystal oscillators (OCXOs) with low-cost
temperature-compensated crystal oscillators (TCXOs) that are stabilized
with frequency information from the SyncE physical layer. The process of
stabilizing the TCXOs is automatic and transparent to the IEEE 1588
clock recovery software.
The IDT 82P33724
and 82P33741
port synchronizers provide independent timing channels for IEEE 1588 and
SyncE; a third independent timing channel is provided for general
purpose rate conversion. Hitless reference switching is supported
between redundant IEEE 1588 references and between redundant SyncE
references. These devices manage IEEE 1588 time and frequency references
by accepting clocks paired with 1 pulse per second (1 PPS) sync signals.
“In addition to providing cost savings by enabling the use of TCXOs,
these new devices deliver the lowest jitter of any IEEE 1588 clock
generators on the market,” said IDT’s Louise Gaulin, vice president and
general manager, Network Communications Division. “These fully featured
devices provide hardware for IEEE 1588 software designers seeking an
efficient and customizable path to develop and deploy a
standards-compliant IEEE 1588 solution.”
Pricing and Availability
Available now, the 1K pricing for SMDs starts at $30.00; and port
synchronizers, $12.00.
