PRODUCT OVERVIEW

What Is the 88E1145-E1-BBM1I000?

88E1145-E1-BBM1I000 is an integrated quad-port Gigabit Ethernet transceiver from Marvell's Alaska® family. The device is part of the 88E1141/88E1145 series, which represents the industry's lowest power, smallest form factor, highest performance, and highest port density Gigabit Ethernet over copper transceiver solution in volume production.

The Alaska Quad 88E1141 and 88E1145 transceivers lead the industry with the lowest power consumption (under 3W for the entire device), enabling network systems manufacturers to decrease system cost by reducing both power supply and fan requirements. Additionally, the 88E1145 device offers the smallest package footprint (21 mm × 21 mm) and requires 40% less board space than competing Gigabit solutions.

The Alaska Quad products offer additional support of 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES). The device supports GMII, RGMII, SGMII, TBI, and RTBI interfaces, providing complete media flexibility with the Media Detect feature that automatically detects and configures to either copper or fiber media. The 88E1145-E1-BBM1I000 is available in a 364-pin BGA package, rated for operation from 0°C to +85°C.

Quad-Port Gigabit Ethernet Highly integrated 4-port device supporting 10/100/1000BASE-T IEEE 802.3 compliant operation with only 0.75W per port.
Integrated 1.25 GHz SERDES Supports 1000BASE-X fiber applications with the Media Detect feature for automatic copper or fiber media configuration.
Flexible MAC Interfaces Supports GMII, RGMII, SGMII, TBI, and RTBI interfaces with four RGMII timing modes, eliminating the need for on-board delay lines.

Circuit Considerations for 88E1145-E1-BBM1I000

Interface Configuration & Media Selection

The 88E1145-E1-BBM1I000 offers flexible interface and media configuration:

  • MAC Interface Selection: Supports GMII/MII, RGMII, SGMII, and serial connections to 10/100/1000 Mbps MAC. RGMII uses 12 lines to reduce pin count and control signals.
  • Media Selection: The HWCFG_MODE[3:0] pins configure the device for copper (RJ45) or fiber (fiber transceiver) media. The Media Detect feature automatically detects and configures the connected media.
  • SGMII Clock Recovery: For serial interfaces without clock recovery, set HWCFG_MODE[3:0] = 0000. For serial interfaces with clock recovery, set HWCFG_MODE[3:0] = 0100.
  • Copper Interface: P[3:0]_MDI[3:0]+ and P[3:0]_MDI[3:0]– pins connect to external RJ45 connectors for 10/100/1000BASE-T operation.
  • Fiber Interface: S_IN+/–, S_OUT+/–, and SD+/– pins connect to fiber transceivers for 1000BASE-X operation.

PCB and System-Level Guidance

Gigabit Ethernet transceiver performance depends on layout and component selection:

  • Power Supply Decoupling: Place low-ESR decoupling capacitors close to each power pin to ensure stable 1.8V supply operation (1.71V to 1.89V).
  • Differential Pair Routing: Route MDI differential pairs with controlled 100Ω differential impedance and matched lengths for optimal signal integrity.
  • Crystal/Clock: Connect a 25 MHz crystal oscillator to XTAL1/XTAL2 pins, or provide a 125CLK input for the integrated SERDES.
  • Thermal Management: The 21 mm × 21 mm BGA package requires adequate copper area and thermal vias for heat dissipation under full load.
  • JTAG Debug: TRST#, TCK, TDI, TMS, and TDO pins support IEEE 1149.1 boundary scan for board-level testing and debugging.
  • Verify the recommended PCB footprint from the official datasheet prior to production.
