Multirate framer takes more onboard
PMC-Sierra reckons the PM5332 Spectra 1x2488 is the industry's highest-density multirate Sonet/SDH framer for single-channel OC-48/STM-16 or four-port channelised OC-12/STM-4 interfaces.

PMC-Sierra reckons the PM5332 Spectra 1x2488 is the industry's highest-density multirate Sonet/SDH framer for single-channel OC-48/STM-16 or four-port channelised OC-12/STM-4 interfaces. The Spectra 1x2488 is the first fully STS-1/AU-3 channelised framer with integrated multirate clock and data recovery (CDR) and synthesis, replacing up to five discrete devices. The highly integrated, small-footprint device enables networking OEMs to easily and efficiently upgrade existing line cards to handle multiple transport operating modes while reducing system cost, complexity, board space, and power.
The Spectra 1x2488 device is ideal for multiservice provisioning platforms, add/drop multiplexers and core routers and switches for both metro and access networks.
Networking OEMs are attempting to develop equipment with higher density, flexible line card upgrades.
By integrating clock and data recovery and clock synthesis on-chip, the Spectra 1x2488 adds multirate capabilities while eliminating the need for a discrete serialiser/deserialiser (serdes) device.
The Spectra 1x2488 device provides a direct interface to small form-factor pluggable (SFP) optical modules, enabling equipment to be field programmable for both OC-48/STM-16 and quad OC-12/STM-4 applications.
This capability allows service providers to purchase one card that may be deployed in multiple applications, saving substantially on maintenance costs, in-service upgrades, and inventory.
The Spectra 1x2488 uses the industry standard TelecomBus interface, enabling seamless interfacing with a wide variety of PMC-Sierra's standard products, as well as customer FPGAs and ASICs.
"With new network equipment costs consuming 40 to 60% of the capital budget, service providers are wary of network equipment migration strategies that require a complete network overhaul", said Steve Perna, vice president and general manager of PMC-Sierra's Service Provider Division.
"The Spectra 1x2488 delivers the highest levels of integration with the lowest power consumption and smallest footprint enabling global equipment manufacturers to migrate to higher capacity and function with seamless line card upgrades.
The Spectra 1x2488 is the latest example of PMC-Sierra's continuation in executing best-in-class OC-48 and OC-12 architectures for metro transport applications".
In STS-1 grooming applications, the Spectra 1x2488 connects to the PM5310 TBS device, enabling automatic protection switching (APS), STS-1 crossconnecting and efficient gigabit Ethernet transport with PM5397 Arrow 2xGE.
In ATM/POS applications, the Spectra 1x2488 connects to the PM7390 S/UNI MACH48 device, allowing ATM and packet termination and mapping for all legal channelisations down to DS3.
In all cases, the multirate line side interface allows a single card design to be software selectable for single-channel OC-48/STM-16 or four-channel OC-12/STM-4 applications.
European and Asian SDH standards add an additional layer of complexity beyond that of the North American Sonet standard.
The Spectra 1x2488 supports worldwide standards and further enables traffic to be transported between Sonet and SDH networks.
This function eliminates the need for additional devices to provide internetworking and is critical to sharing information globally between North America, Europe and Asia.
The PM5332 Spectra 1x2488 is a 3.5W, 1.8V CMOS device packaged in 31 x 31mm 500-pin UBGA package.
A comprehensive support package including reference design and applications notes is available on PMC-Sierra's website.
