Xilinx Virtex-6 HXT FPGAs Deliver Superior Transceiver Performance for Wired Optical Communications
Xilinx announced the immediate availability of Virtex(R)-6 HXT FPGAs that support 40Gbps and 100Gbps line cards with flexible port configurations including 1x40Gbps, 4x10Gbps, 1x100Gbps and 10x10Gbps. Additionally, Virtex-6 HXT FPGAs support the long reach optical requirements of next generation communications equipment without the need for costly external re-timer circuitry through market leading transceiver jitter performance.
Xilinx Virtex-6 HXT devices seamlessly interface to industry standard SFP+, XFP, and CFP optical modules at line rates up to 11.18Gbps addressing next generation optical transport application needs. Furthermore, through superior jitter performance - sub 500 fs rms random jitter at 11.18Gbps - and signal integrity, the need for external conditioning circuitry is eliminated. The superior jitter performance provides the system designer the margin required to build robust high speed interfaces.
As the communications network infrastructure moves towards 40Gbps and 100Gbps port rates, the need for high performance optical jitter compliant transceivers is a critical component for success, said Krishna Rangasayee, Corporate Vice President and General Manager of Xilinx's Communications Business Unit. Xilinx's Virtex-6 HXT device meets those optical standards and requirements while offering the flexibility and customization only available in a programmable logic device.
Virtex-6 HXT Devices Features
Optimized for applications that require ultra high-speed serial connectivity, Virtex-6 HXT FPGAs offer the industry's highest serial bandwidth through a combination of 6.6Gbps GTX transceivers and 11.18Gbps GTH transceivers to enable next-generation packet and transport, switch fabric, video switching, and imaging equipment. To enable these applications, Virtex-6 HXT devices also feature:
* A ground up design that is optimized for 10G signaling - including Transmit (Tx) pre-emphasis, Receive (Rx) linear equalization and Decision Feedback Equalizer (DFE) to meet the tough jitter requirements.
* Lower jitter with superior DFE and EQ circuits, higher total transceiver count, more BRAM and highest number of SERDES capabilities.
* Design topology that isolates the high performance analog circuits from the noisy digital logic and IO providing superior noise performance.
* A ground up package design with all serial pins isolated from parallel IO, in-package power planes and capacitors, and a sparse-chevron pinout resulting in 40 dB of isolation between Tx and Rx and 30dB of isolation between channels.
* Overall Virtex-6 HXT device performance enables the designer to interface to optical modules directly without the need for external re-timers, thereby saving on bill-of-materials cost, power dissipation and board real estate.
