1. Link Core Components
4.1
The physical (Phy) interface provides Phy-level services to the transmitter and receiver. This includes
gaining access to the serial bus, sending packets, receiving packets, and sending and receiving
acknowledge packets. The Phy interface module also interfaces to the Phy chip and implements Texas
Instruments patent-pending bus-holder galvanic isolation.
4.2
Transmitter
The transmitter retrieves data from either the asynchronous transmit FIFO (ATF) or the data mover (DM)
port and creates correctly formatted serial-bus packets to be transmitted through the Phy interface. When
data is present at the ATF interface to the transmitter, the TSB12LV32 Phy interface arbitrates for the serial
bus and sends a packet. When data is present at the DM Port, the TSB12LV32 arbitrates for the serial bus
during the next isochronous cycle. The transmitter autonomously sends the cycle-start packets when the
chip is a cycle master.
4.3
Receiver
The receiver takes incoming data from the Phy interface and determines if the incoming data is addressed
to this node. When the incoming packet is addressed to this node, the CRC of the packet is checked. If the
header CRC is good, the header is confirmed in the general-receive FIFO (GRF). For block and isochronous
packets, the remainder of the packet is confirmed one quadlet at a time. The receiver places a status quadlet
in the GRF after the last quadlet of the packet is confirmed in the GRF. The status quadlet contains the error
code for the packet. In the case of asynchronous packets, the error code is the acknowledge code that is
sent (returned) for that packet. For isochronous and broadcast packets that do not need acknowledge
packets, the error code is the acknowledge code that would have been sent. This acknowledge code tells
the transaction layer whether or not the data CRC is good or bad. If the header CRC is bad, the header is
flushed and the rest of the packet is ignored. When a cycle-start packet is received, it is detected and the
cycle-start packet data is sent to the cycle timer. Cycle-start packets are not placed in the GRF like other
quadlet packets.
