Transcript

  • 1. Mini PHYTER® 10/100 Ethernet Transceivers
    • Source: National Semiconductor
  • 2. Introduction
    • Purpose
      • This training module provides an overview of mini PHYTER transceivers and their operations.
    • Outline
      • Introduction of OSI Reference model & IEEE802.3
      • Overview of Mini PHYTER family
      • Introduction of 3 basic functions
      • Introduction of design guidelines
    • Content
      • 15 pages
  • 3. Open System Interconnect (OSI) Model
    • The OSI Reference model defines 7 layers that describe how data or information travels from one device to another over a network.
    Programs that use the data Purpose Data is extracted, formatted, & decrypted Defines the period during which data can be used Moving the data Sending packets on the network Format of the data frame Electrical signal conventions
  • 4. OSI Model vs. IEEE 802.3
  • 5. Mini PHYTER ®
    • PHYTER mini products are designed for robust operation to meet the needs of a variety of end user applications.
      • High End Peripheral Devices
      • Industrial Controls
      • Factory Automation
      • General Embedded Applications
  • 6. PHYTER® Mini Selection Guide
  • 7. Operation Modes
    • Two modes of operation
      • Media Independent Interface (MII) Mode – is used to connect PHY devices to a MAC in 10/100 Mb/s systems.
      • Reduced Media Independent Interface (RMII) – is used to connect PHY devices to a MAC in 10/100 Mb/s systems using a reduced number of pins.
    • The modes of operation can be selected by strap options or register control.
  • 8. 100BASE-TX Transmit Function
    • Functional blocks
      • Code-group Encoder and Injection block
      • Scrambler block (bypass option)
      • NRZ to NRZI encoder block
      • Binary to MLT-3 converter / Common Driver
  • 9. 100BASE-TX Receive Function
    • Functional blocks
      • Analog Front End
      • Digital Signal Processor
      • Signal Detect
      • MLT-3 to Binary Decoder
      • NRZI to NRZ Decoder
      • Serial to Parallel
      • Descrambler
      • Code Group Alignment
      • 4B/5B Decoder
      • Link Integrity Monitor
      • Bad SSD Detection
  • 10. 10BASE-T Transceiver Function
    • IEEE 802.3 compliant
    • Operation modes
      • Half Duplex mode
      • Full Duplex mode
    • Smart Squelch to determine when valid data is present on the differential receive inputs.
    • Collision is detect when the receive and transmit channels are active simultaneously.
    • Signal Quality Error (SQE) indicates successful transmission
    • The link pulse generator produces pulses as defined in the IEEE 802.3 10BASE-T standard.
    • The jabber function monitors the transmitter’s output.
    • The encoder begins operation when the Transmit Enable input is active and converts NRZ data to pre-emphasized Manchester data for the transceiver.
    • The decoder detects the end of a frame when no additional mid-bit transitions are detected.
  • 11. Reset Operation
    • Hardware Reset
      • All registers will be re-initialized to default values.
      • The hardware configuration values will be re-latched into the device.
    • Software Reset
      • All registers will be re-initialized to default values.
      • The hardware configuration values will be maintained.
  • 12. Design Guideline – TPI Connection
  • 13. Design Guideline – Clock Requirement
    • The mini PHYTER supports an external CMOS level oscillator source or a crystal resonator device.
    Oscillator Circuit Crystal Oscillator Circuit
  • 14. Design Guideline – Power Supply
    • Power Feedback Connection
    • The device can be put in a Power Down mode by setting bit 11 (Power Down) in the Basic Mode Control Register,
