Features
- 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.
|
- 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 outputs with selectable pre-emphasis per port to counteract dielectric losses and allow maximum reach on printed circuit boards.
- Selectable receive input equalization provides robust data recovery of highly degraded input signals.
- 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 Ω or 150 Ω differential is selectable.
- Source output impedance of 100 Ω or 150 Ω differential is programmable.
|
|
- Digital Loss of Link (DLOLB) detect pin outputs for monitoring individual or multiple links. DLOLB can be programmed to indicate excessive 8B/10B code error rate, loss of synchronization, loss of signal, CRC32 errors, or comma density.
- Supports optional 2-pin serial management interface using selectable Two-Wire Interface (TWI) or MDC/MDIO protocol for configuration and diagnostic access.
- For normal mode of operation, a management interface is not required.
|
- External control pins can be over-ridden by registers.
- Provides a standard 5-signal IEEE 1149.1 JTAG test port for boundary scan board testing purposes.
|
- 0.18 µ CMOS, 1.8 V and 3.3 V supply.
- Small 15 mm x 15 mm footprint, 196-pin CABGA with 1 mm ball pitch.
|
- Ultra-low operating power of 1.3 W typical with all 4 channels active at 2.125 G.
