Reference design for delivering advanced
communication services over low-cost packet n/ws
Vitesse Semiconductor Corporation and Zarlink Semiconductor
has announced availability of a joint reference design that
delivers synchronization required by carriers to deliver
scalable, higher bandwidth communication services over packet-based
The reference design combines Vitesse's VSC8574 Gigabit
Ethernet (GE) PHY transceiver and Zarlink's ZL30143 Synchronous
Ethernet (SyncE) dual channel system synchronizer. The Vitesse
PHY provides both primary and secondary recovered clock
outputs as clock references to Zarlink's ZL30143 in the
synchronous timing system to provide a low jitter Synchronous
Ethernet solution. The reference design meets the performance
demands for timing synchronization in accordance with ITU-T
Recommendation G.8262 for wireless base stations, radio
network controllers, gateways, aggregation and transmission
equipment, and routers while reducing design complexity.
For applications requiring IEEE 1588v2 phase and time synchronization,
Vitesse's VSC8574 device provides both one-step and two-step
time stamping in the physical layer with +/-10ns or better
accuracy and can be complemented with Zarlink's ZL3034x
family of IEEE 1588v2-enabled timing products.
"Packet-based Ethernet technologies enable carriers
to cost-effectively scale bandwidth to meet the demands
of new mobile multimedia applications," said Jamileh
Davoudi, product marketing manager with Zarlink's Timing
and Synchronization product line. "Vitesse and Zarlink
have combined our Synchronous Ethernet timing expertise
to provide manufacturers with an easy-to-implement solution
to support multiple services over a single network. In addition,
this reference design allows the flexibility to upgrade
designs to IEEE 1588v2 for wireless technologies, such as
WCDMA-TDD, CDMA2000 and Mobile WiMAX."
"Our reference design with Zarlink gives equipment
manufacturers and service providers a seamless upgrade path
to integrate precise timing features required to deliver
advanced communication services over lower-cost packet networks,"
said Brian Jaroszewski, senior product manager at Vitesse.
"Complemented by our broad Carrier Ethernet portfolio
of GE, 10GE and OTN PHY devices with physical layer IEEE
1588v2 support, Vitesse offers full network synchronization
support sufficient for WiMAX and LTE backhaul, as well as
other timing critical applications."
