(vct?) feature, which uses time domain reflectometry (tdr) technology for the remote identification of po tential cable malfunctions, thus reducing equipment returns and service calls. using vct, the alaska 88E1116R device detects and reports potential cabling issues such as pair swaps, pair polarity and excessive pair skew. the device will also detect cable opens, shorts or any impedance mis- match in the cable and reporting accurately within one meter the distance to the fault. the 88E1116R device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a gigabit per second data rate. the device achieves robust performance in noisy environments with very low power dissipation. f eatures ? 10/100/1000base-t ieee 802.3 compliant ? four rgmii timing modes - this eliminates the need for adding trace delays on the pcb ? supports lvcmos, sstl, and hstl i/o stan- dards on the rgmii interface ? integrated mdi interface termination resistors that eliminate twelve passive components ? energy detect and energy detect+ low power modes ? three loopback modes for diagnostics ? ?downshift? mode for two-pair cable installations ? fully integrated digital adaptive equalizers, echo cancellers, and crosstalk cancellers ? advanced digital baseline wander correction ? automatic mdi/mdix crossover at all speeds of operation ? automatic polarity correction ? ieee 802.3u compliant auto-negotiation ? software programmable led modes including led testing ? supports ieee 1149.1 jtag ? mdc/mdio management interface ? crc checker, packet counter ? packet generation ? virtual cable tester (vct) ? auto-calibration for mac interface outputs ? coma mode support ? requires a single 1.8v supply ? i/o pads can be supplied with 1.8v, 2.5v, or 3.3v ? two regulators generate all required voltages. regulator can be supplied with 1.8v, 2.5v or 3.3v. ? commercial grade ? 64-pin qfn package 88E1116R device used in copper application m a g n e t i c s mac interface - rgmii media types: - 10base-t - 100base-tx - 1000base-t rj-45 10/100/1000 mbps ethernet mac 88E1116R device integrated passive termination
