OC-12/OC-48/OC-192 OC-12/OC-48/OC-192 SerDes Transceiver with Amplif-Eye3TM M 2 7 2 1 8 Octal SkyRailTM The M27218 M27218 from Mindspeed TechnologiesTM is a lowpower, high-density, eight-channel SerDes transceiver capable of operating from 400 Mbps to 2.5 Gbps. The M27218 M27218 has been optimized for telecom applications that require serial LVDS (SLVDS)/CML interface to operate at 2.488 Gbps (OC-48 OC-48) or 622 Mbps (OC-12 OC-12). Many system line cards, switch cards, and port cards in use today are designed with parallel LVDS (PLVDS) interfaces running un-encoded or unscrambled data through the backplane. As data throughput requirements increase, system vendors are challenged to upgrade existing equipment without forcing customers to replace their line cards, port cards or entire systems. The integration of today's un-encoded traffic with high-speed serial traffic has proven to be a major obstacle for systems designers. Mindspeed's M27218 M27218 solves these problems by providing a seamless upgrade from PLVDS backplanes to highspeed SLVDS/CML in a single device. System designers are able to provide a cost effective means of upgrading their customer's systems with a 4X increase in data throughput. Customers are able to preserve their investments in existing equipment and maintain software compatibility. The device integrates eight serial SLVDS/CML transmitters and eight serial receivers that can adapt and interface to LVDS or CML/LVPECL inputs/outputs. It also integrates 32 parallel LVDS (PLVDS) transmitters and 32 parallel receivers, selectable 4:1/1:4, 2:1/1:2 and 1:1 serializer and de-serializer functions, clock and data recovery, synthesis circuitry, termination resistors and de-skew buffers. The M27218 M27218 has built in Amplif-Eye3TM signal conditioning circuitry that provides optimal signal integrity over standard FR-4 PCB trace and legacy connectors. > K E Y F E AT U R E S > First Octal SerDes transceiver optimized for existing telecom backplane applications able to run at 622Mbps and 2.488Gbps to provide an easy upgrade from 622Mbps (OC-12 OC-12) to 2.488 Gbps (OC-48 OC-48) > Adaptive high-speed interface between LVDS and CML > Capable of accepting more than 1,000 consecutive identical digits optimum signal integrity over standard FR-4 and legacy connectors > Total power consumption of less than 2.5 W at 2.488 Gbps > FlexilinkTM PLVDS interface enables synchronous and asyn-chronous operation, simplifies system design and provides multiple clocking modes for fast implementation and time to market > Amplif-Eye3TM signal conditioning > Serial Peripheral Interface (SPI) for easy control, circuitry with programmable programming and monitoring pre-emphasis and equalization, of all features in the device low-jitter and 50 mV receiver input sensitivity provides This third generation of Amplif-EyeTM technology includes transmitter pre-emphasis, receiver equalization, and other patented circuitry. The M27218 M27218 high-speed SLVDS/CML transmitters include multiple levels of pre-emphasis configurable per channel to optimize the performance required to drive more than 1.5 meters (60 inches) of FR-4 backplane material and 2 connectors at 2.488 Gbps. The M27218 M27218 high-speed SLVDS/CML receivers include equalizers to further improve signal integrity over highly attenuated backplanes. The swing of the M27218 M27218 SLVDS/CML output is also programmable on an individual-channel basis to achieve interoperability with legacy SerDes devices and optimize the device for power and distance. > West Line Card ASIC OC-12/ OC-12/ STM-4, OC-48/ OC-48/ STM-16 STM-16 OC-192/ OC-192/ STM-64 STM-64 622 Mbps or 2.488 Gbps 622 LVDS M27218 M27218 M27218 M27218 M27218 M27218 M27218 M27218 Switch Cards Line Card East 622 Mbps or 2.488 Gbps 622 LVDS M27218 M27218 Active M27218 M27218 Redundant 622 LVDS 622 LVDS 622 LVDS ASIC Crossconnect ASIC OC-12/ OC-12/ STM-4, OC-48/ OC-48/ STM-16 STM-16 OC-192/ OC-192/ STM-64 STM-64 Line Cards: OC-12 OC-12 /STM-4 OC-48/STM-16 OC-48/STM-16 OC-192/ OC-192/ STM-64 STM-64 Crossconnect ASIC 622 LVDS 622 LVDS M27218 M27218 622 LVDS M27218 M27218 M27218 M27218 Combination of 622 Mbps and 2.488 Gbps Combination of 622 Mbps and 2.488 Gbps Port Cards: 218 Port Card T1/E1,T3/E3,E4,OC-3/STM-1, OC-12/STM-4 OC-12/STM-4, 10/100BaseT, 1GE, etc. M27218 M27218 enables seamless upgrade to OC-192/STM-64 OC-192/STM-64, SONET/SDH ring and 4X increase in capacity Product Highlights Features · AC and DC coupling capability · Eight channel SerDes with highspeed SLVDS/CML I/O capable of operating from 400 Mbps to 2.5 Gbps, with performance optimized for 622Mbps and 2.488 Gbps · Channel alignment for each section of four PLVDS receive channels · Word boundary alignment capability · Capable of accepting more than 1,000 consecutive identical digits · 32 PLVDS I/Os capable of bit rates from 400 Mbps to 800 Mbps · Built-in Self Test (BIST)with PRBS pattern generation · Full-speed mode, 4:1 Mux/DeMux to map four PLVDS I/O parallel data to one SLVDS/CML I/O serial data · Parallel and reverse loopback modes for device and link testing · Pass-through mode to map one PLVDS I/O parallel data to one SLVDS/CML I/O serial data · Serial Peripheral Interface (SPI) for easy control, programming, monitoring of all features in the device · Amplif-Eye3 highly programmable signal conditioning circuitry for optimum performance over long cables and PCB (FR-4) trace lengths in excess of one meter · Power dissipation is estimated at less than 2.5 W @ 2.488 Gbps · Individual SLVDS/CML channel or entire chip power down capability · Four way programmable output swing between 500 mV and 1000 mV differential peak-to-peak · Built-in 50 Ohm termination resistors on SLVDS/CML and PLVDS interfaces www.mindspeed.com/salesoffices General Information: (949) 579-3000 Headquarters Newport Beach 4000 MacArthur Blvd., East Tower Newport Beach, CA 92660-3007 27218-BRF-001-A 27218-BRF-001-A M02-0649 M02-0649 · Fast serial bit rate reduces number of interconnects in high-end networking equipment · Integration of 8 channels in one device reduces system cost and board space · FlexilinkTM interface simplifies the timing interface and system design, while enabling the M27218 M27218 to interface to a variety of different chips · Fully integrated design with no external components for design simplicity and optimal board layout · Amplif-Eye3 signal conditioning circuitry enables best signal integrity over FR-4 material · 324-ball fine-pitch HSBGA package (23 mm x 23 mm); 1.8 V core supply · Low power dissipation for high level of system integration and high port densities Benefits Applications · Seamless backplane upgrade path from 622 Mbps to 2.488 Gbps · High-speed serial backplane interconnects · Can interface with existing parallel LVDS line cards and automatically adjust to 2.488 Gbps CML outputs · Multi-purpose chassis-to-chassis serial connections Ideal For · SONET/SDH Add/drop multiplexers · Optical cross-connects · Network aggregators · WAN access concentrators · High-end and midrange routers · Enterprise and carrier-class switches · High-end video equipment and graphic cards · High-speed automatic test equipment and high-bandwidth testers Ordering Information The M27218 M27218 device will be available in three data rate options: M27218-1 M27218-1 Up to 1.25 Gbps M27218-2 M27218-2 Up to 2.5 Gbps © 2004 Mindspeed TechnologiesTM.
