High-density T1/E1 processing solution
PMC-Sierra has introduced the PM4328 TECT3, the newest member of the TEMUX product family that is optimised for channelised DS3 applications.
The SQN2130 is designed to support the manufacture of any size basestation - femto, pico, micro or multisector macro - and can serve multiple thousands of simultaneous users.
PMC-Sierra's PM8800 WiZIRD 2Tx/2Rx is the industry's highest density WiMAX RF IC solution integrating full 2Tx/2Rx MIMO capability, multiband support, direct-conversion ZIF RF transceiver, analogue and digital converters, and an industry-standard JEDEC JESD207 compliant baseband digital interface in a single device.
The dual-radio path PM8800 WiZIRD 2Tx/2Rx eliminates the need for multiple radio devices and provides programmability to support multiple frequency bands for worldwide WiMAX roaming.
The device supports 64QAM modulation for both transmit paths at 0dBm output power level with an EVM performance that addresses a spectrum of WiMAX solutions from basestation applications to mobile subscriber solutions.
"PMC-Sierra delivers the only RFIC with the features needed for femtocell applications", says Bernard Aboussouan, Vice President of Marketing and Business Development for Sequans.
"These include support for higher modulation, higher output power, 2Tx/2Rx configuration, and multiple frequency bands".
"Our collaboration delivers a high performance solution with an overall hard-to-beat bill of materials that is of paramount importance in the success of global WiMAX deployment".
"Our combined solution provides tremendous value to WiMAX OEMs and ODMs who can now address multiple territories with a single cost-effective design, and to WiMAX operators who can extend coverage and minimise capital investment", says Tom Sun, Vice President and General Manager for PMC-Sierra's Broadband Wireless Division.
The Sequans/PMC-Sierra femtocell reference design includes support for network synchronisation, a key requirement for applications such as SOHO deployments, which can be performed using either GPS or over the network via IEEE1588v2.
Sequans and PMC-Sierra are also collaborating on multiband CPE and will deliver reference designs featuring Sequans SQN1130 baseband and PMC-Sierra's PM8800 WiZIRD RFIC.
