简  介:PM8372 PBC 4x2G Preview 4-Port FC/GE Retimer and FC-AL Port Bypass Controller 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. TEST AND CONTROL 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. Digital Loss of Link (DLOLB) detect 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. Interrupt output to flag changes in bypass state and DLOLB error conditions……
