• Includes Electronic Dispersion Compensation (EDC) meeting SFF-8431 requirements for extended reach
• Provides host-side interface flexibility with 40GBASE-R4, RXAUI, XAUI, and 1000BASE-X support
• Enables programmable signal transitions and adjustable transmitter amplitude/pre-emphasis

Applications

• High-density line cards with SFP+ ports
• SFP+ modules and 10G SFP+ copper direct attach cables
• 1G SFP module implementations
• Switch-to-switch bridging modes

Procurement Notes

Verify the specific ordering suffix BKP2C000 against official Marvell documentation to confirm exact manufacturing lot, temperature grade, and packaging configuration. Ensure that any assumed functional differences based on suffix variations are validated by the manufacturer's datasheet rather than distributor generalizations.

Selection Notes

Select this component when designing systems requiring multi-standard support for 10G and 1G Ethernet alongside 40G aggregation capabilities. The integrated EDC makes it suitable for applications utilizing OM1/OM2/OM3 fiber or long-reach single-mode fiber without external equalization. Verify that the host system can accommodate the required 324-pin FCBGA footprint and thermal dissipation profile.
