DESCRIPTION
The TSB12LV32 (GP2Lynx) is a high-performance general-purpose IEEE 1394a-2000 link-layer controller (LLC)
with the capability of transferring data between the 1394 Phy-link interface, an external host controller, and an
external device connected to the data-mover port (local bus interface). The 1394 Phy-link interface provides the
connection to a 1394 physical layer device and is supported by the LLC. The LLC provides the control for
transmitting and receiving 1394 packet data between the microcontroller interface and the Phy-link interface via
internal 2-Kbyte FIFOs at rates up to 400 Mbps. The TSB12LV32 transmits and receives correctly formatted
1394 packets, generates and detects the 1394 cycle start packets, communicates transaction layer transmit
requests to the Phy, and generates and inspects the 32-bit cyclic redundancy check (CRC).
The TSB12LV32 is capable of being 1394 cycle master (CM), 1394 bus manager, 1394 isochronous resource
manager (IRM) if additional control status registers (CSRs) are added via the external host controller, and
supports reception of 1394 isochronous data on two channels and transmission of 1394 isochronous data on
four channels.
The TSB12LV32 supports a direct interface to many microprocessors/microcontrollers by including
programmable endian swapping. TSB12LV32 has a generic 16-/8-bit host bus interface which includes support
for a ColdFireE microcontroller mode at rates up to 60 MHz. The microcontroller interface can operate in byte or
word (16 bit) accesses.
