• High-Speed SERDES  Four SERDES channels with per-channel data rates up to 3.7 Gbps enable XAUI, Fibre Channel and multi-gigabit backplane links with built-in Rx CDR and transmitter preemphasis.
• Embedded Memory  Approximately 0.11 Mbits (113,664 bits) of on-chip RAM suitable for FIFOs, buffers and small lookup tables.
• I/O and Package  204 user I/O pins in a 484-ball BBGA (23×23) surface-mount package provide high routing density for board and backplane interfaces.
• System Gates  Device delivers up to 643,000 system gates for mixed embedded/core logic implementations.
• Power and Voltage  Operates across a flexible supply range from 1.425 V to 3.6 V to support multiple I/O standards and system architectures.
• Operating Range and Grade  Commercial-grade device rated for 0 °C to 70 °C operation and RoHS compliant for regulatory alignment.
• Surface-Mount Packaging  484-FPBGA (23×23) package supports high-density board layouts in surface-mount assembly flows.

Typical Applications

• Backplane Data Transmission  High-speed SERDES channels and built-in Rx clock recovery make the ORT42G5-1BMN484C suitable for multi-gigabit backplane interconnects.
• 10 Gigabit Ethernet Bridging  Use the device to implement XAUI interfaces and configurable backend logic for 10 GbE bridging and aggregation functions.
• Fibre Channel and Storage Networking  Embedded 8b/10b encoding/decoding and link-state functions enable Fibre Channel protocol handling and storage fabric connectivity.
• Switch Fabric and Line Card Links  Four high-speed channels allow designers to implement work and protection links between line cards and switch fabrics in networking equipment.

Unique Advantages

• Integrated High-Speed Transceivers:  Four SERDES channels operating to 3.7 Gbps reduce external components and simplify high-speed link implementation.
• Substantial Logic Capacity:  10,368 logic elements and up to ~643k system gates provide headroom for protocol stacks, buffering and custom datapath logic.
• High I/O Density in a Compact BGA:  204 I/O in a 484-ball BBGA (23×23) enables dense routing for complex board and backplane interfaces.
• Flexible Power Options:  Wide supply range (1.425 V–3.6 V) supports diverse system voltage requirements and multiple I/O standards.
• On-Chip Memory Resources:  Approximately 0.11 Mbits of embedded RAM for FIFOs, alignment buffers and temporary data storage without external SRAM.
• Commercial-Grade, RoHS Compliant:  Commercial temperature rating and RoHS compliance support mainstream networking and communications products.
