Description

The 88E1116A1-NNC1C000 is an electronic component belonging to the IC chip product category. It is a Gigabit Ethernet transceiver that implements the Ethernet physical layer portion of the 1000BASE-T, 100BASE-TX, and 10BASE-T standards. The transceiver contains the active circuitry required to transmit and receive data on standard CAT 5 unshielded twisted pair.

Specifications and features

• 10/100/1000BASE-T IEEE 802.3 compliant
• Four RGMII timing modes - eliminates the need for adding trace delays on the PCB
• Supports LVCMOS, SSTL, and HSTL I/O Standards 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, and 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

Application Scenarios

The 88E1116A1-NNC1C000 can be used in networking devices and systems where a Gigabit Ethernet connection is required.

Comparison

• Supports multiple I/O standards on the RGMII interface, providing greater flexibility to the user.
• Integrated MDI interface termination resistors eliminate the need for twelve passive components, simplifying the design and reducing the overall cost and footprint of the device.
• Fully integrated digital adaptive equalizers, echo cancellers, and crosstalk cancellers provide greater signal integrity and reduce the design complexities for users.

• Not suitable for applications that require data transmission over other cable media besides standard CAT 5 unshielded twisted pair.
• Requires a single 1.8V supply, limiting the power supply options for the device.
