OC-12/OC-48/OC-192 SerDes Transceiver with Amplif-Eye3
Octal SkyRailM27218 from Mindspeed Technologiesis lowpower, high-density, eight-channel SerDes transceiver capable operating from Mbps Gbps. M27218 been optimized telecom applications that require serial LVDS (SLVDS)/CML interface operate 2.488 Gbps (OC-48) Mbps (OC-12). Many system line cards, switch cards, port cards today designed with parallel LVDS (PLVDS) interfaces running un-encoded unscrambled data through backplane. data throughput requirements increase, system vendors challenged upgrade existing equipment without forcing customers replace their line cards, port cards entire systems. integration today's un-encoded traffic with high-speed serial traffic proven major obstacle systems designers. Mindspeed's M27218 solves these problems providing seamless upgrade from PLVDS backplanes highspeed SLVDS/CML single device. System designers able provide cost effective means upgrading their customer's systems with increase data throughput. Customers able preserve their investments existing equipment maintain software compatibility. device integrates eight serial SLVDS/CML transmitters eight serial receivers that adapt interface LVDS CML/LVPECL inputs/outputs. also integrates parallel LVDS (PLVDS) transmitters parallel receivers, selectable 4:1/1:4, 2:1/1:2 serializer de-serializer functions, clock data recovery, synthesis circuitry, termination resistors de-skew buffers. M27218 built Amplif-Eye3signal conditioning circuitry that provides optimal signal integrity over standard FR-4 trace legacy connectors.
First Octal SerDes transceiver optimized existing telecom backplane applications able 622Mbps 2.488Gbps provide easy upgrade from 622Mbps (OC-12) 2.488 Gbps (OC-48) Adaptive high-speed interface between LVDS Capable accepting more than 1,000 consecutive identical digits optimum signal integrity over standard FR-4 legacy connectors Total power consumption less than 2.488 Gbps FlexilinkPLVDS interface enables synchronous asyn-chronous operation, simplifies system design provides multiple clocking modes fast implementation time market
Amplif-Eye3signal conditioning Serial Peripheral Interface (SPI) easy control, circuitry with programmable programming monitoring pre-emphasis equalization, features device low-jitter receiver input sensitivity provides
This third generation Amplif-Eyetechnology includes transmitter pre-emphasis, receiver equalization, other patented circuitry. M27218 high-speed SLVDS/CML transmitters include multiple levels pre-emphasis configurable channel optimize performance required drive more than meters inches) FR-4 backplane material connectors 2.488 Gbps. M27218 high-speed SLVDS/CML receivers include equalizers further improve signal integrity over highly attenuated backplanes. swing M27218 SLVDS/CML output also programmable individual-channel basis achieve interoperability with legacy SerDes devices optimize device power distance.
