transceiver solutions product overview the marvell alaska family of gigabit ethernet (gbe) over copper transceivers are the industry?s lowest power, smallest form factor, highest performance, and highest port density solutions in volume production. targeted at high-density gbe switches, the alaska quad transceivers are single-chip devices containing four independent gbe phys on a single monolithic ic. each transceiver performs all of the physical layer functions for 100base-tx and 1000base-t full or half duplex ethernet on category 5 (cat 5) twisted pair cable, and 10base-t full or half duplex ethernet on cat 3, 4 and 5 cable. the alaska quad devices (88E1040s, 88e1041s and 88e1042h) offer additional support of 1000base-x through an integrated 1.25 ghz serializer/deserializer (serdes). features highly integrated 4-port device ultra low power, just exceeding 1w/port 10/100/1000base-t ieee 802.3 compliant supports gmii/rgmii/tbi/rtbi interfaces virtual cable tester tm feature integrated 1.25 ghz serdes (881040s, 88e1041s, 88e1042h) media detect feature automatically detects and configures to either copper or fiber media automatic support for 2-pair cat 5 cable (100 mbps) power management modes four rgmii timing modes user configurable independent media access controller (mac) interface select benefits enables highly integrated gigabit switches enables higher integration and reduced cost compatibility with existing installed base of compliant devices reduces cost and simplifies pcb layout remote cable diagnostics for fault detection supports 1000base-x fiber applications complete media flexibility operates over installed 2-pair cable reduced system power eliminate the need for on-board delay lines allows interface flexibility p0_led_link10 p0_led_link100 p0_led_link1000 p0_led_duplex p0_led_rx p0_led_tx gconfig[0] trst# tck tdi tms tdo 10/100/1000 receive pcs 10/100/1000 transmit pcs fiber channel transmit (parts with s or h option only) management interface led/ configuration bias/test registers auto-negotiation p0-mdi[3:0]+/- p0_tx_en p0_tx_er p0_txd[7:0] p0_gtx_clk p0_tx_clk p0_rx_dv p0_rx_er p0_rxd[7:0] p0_rx_clk p0_crs p0_col xtal1 xtal2 reset# 125clk p0_s_in+/- p0_s_clk+/- p0_s_out+/- p0_mdc p0_mdio p0_int# p0_rset p0_hsdac+/- p0_tstpt timing control d/a waveshape filter a/d skew control feed forward equalizer dpll trellis decoder decision feedback equalizer echo canceller near end crosstalk canceller clock/reset jtag active hybrid gain control baseline 10base-t receiver fig 1. alaska quad gbe transceiver block diagram alaska quad gigabit ethernet transceivers 88E1040/s, 88e1041/s, 88e1042h
