Embedded Function Features
Provides a line-interface to system-interface with various system standards such as OC-192/STM-64
SONET/SDH, quad OC-48/STM-16 10 Gbits/s Ethernet, and 10 Gbits/s OTN (digital wrapper/strong FEC) or
12.5 Gbits/s SuperFEC.
Embedded PLLs with programmable M/N multiplication/division values provide exible data rate conversion
between line side and system side.
Line-side supports 16-bit LVDS data with multiple line frequencies supported up to 850 MHz, depending on sys-
tem standard.
Line-side interface, including timing and jitter specications, compliant to OIF 99.102.5 standard.
Receive-side interface can be split into four separate asynchronous 2.5 Gbits/s interfaces (4-bit LVDS data inter-
face for each) with a separate clock for each for transfer to the FPGA logic.
Data and clock rates divided by 4 or 8 for use in FPGA logic.
LVDS I/Os compliant with EIA
-644 support hot insertion. All embedded LVDS I/Os include both input and output
on-board termination to allow high-speed operation.
Low-power LVDS buffers.
Intellectual Property Features
Programmable logic provides a variety of yet-to-be standardized interface functions, including the following IP core
functions:
10 Gbits/s Ethernet Physical Coding Sublayer (PCS), as dened by IEEE 802.3ae:
– XGMII for interfacing to 10 Gbits/s Ethernet MACs. XGMII is a 156 MHz double data rate parallel short-reach
(typically less than 3 in.) interconnect interface.
– Elastic store buffers for clock domain transfer to/from the XGMII interface.
–X
59 + X39 + X1 scrambler/descrambler for 10 Gbits/s Ethernet.
– 64b/66b encoders/decoders for 10 Gbits/s Ethernet.
– Idle insertion and deletion.
– SMI interface for control and status.
Quad 2.5 Gbits/s SONET/SDH to 10 Gbits/s SONET/SDH MUX/deMUX functions.
Programmable Features
High-performance programmable logic:
– 0.16 m 7-level metal technology.
– Internal performance of >250 MHz.
