GENERAL

? Supports 4 Fibre Channel Physical Interfaces at 1.0625 or 2.125 Gbit/s per Fibre Channel – Physical Interface (FC-PI) or 4 Gigabit Ethernet Retimers at 1.25 Gbit/s per IEEE 802.3z.

? Each port supports FC 1G or 2G rate detection/auto-selection.

? Supports Arbitrated Loop and Retimer configuration.

? Each port is independently selectable to perform retimer, reclocker or bypass-path function.

? Non-blocking crossconnect supports protection switching, broadcasting and multicasting.

? Automatic selection of retimer, reclocker or bypass-path function to minimize latency and jitter when a disk is bypassed.

? Per-port receive monitoring for loss of signal, error rate, and link level violations.

? Supports single-ended or differential 106.25 MHz reference clock REFCLK for Fibre Channel applications or 125 Mhz reference clock for Gigabit Ethernet applications.

HIGH-SPEED INTERFACE

? High-speed outputs with selectable preemphasis per port to counteract dielectric losses and allow maximum reach on printed circuit boards.

? Selectable receive input equalization for improved signal integrity.

? Minimized board footprint and improved signal integrity achieved because:

? No external components are required to interface the high-speed signals to optics, coax, or serial backplanes using the internal AC coupling capacitors and terminating resistors.

? Receive input termination of 100 ? or 150 ? differential is selectable.

? Source output impedance of 100 ? or 150 ? differential is programmable.
