The TSB12LV01B provides a high-performance IEEE 1394-1995 interface with the capability of transferring data between the 32-bit host bus, the 1394 PHY-link interface, and external devices connected to the local bus interface. The 1394 PHY-link interface provides the connection to the 1394 physical (PHY) layer device and is supported by the link-layer controller (LLC). The LLC provides the control for transmitting and receiving 1394 packet data between the FIFO and PHY-link interface at rates of 100 Mbits/s, 200 Mbits/s, and 400 Mbits/s. The TSB12LV01B transmits and receives correctly-formatted 1394 packets and generates and inspects the 32-bit cyclic redundancy check (CRC). The TSB12LV01B is capable of being cycle master and supports reception of isochronous data on two channels. TSB12LV01B has a generic 32-bit host bus interface, which will connect to most 32-bit hosts. The LLC also provides the capability to receive status from the physical layer device and to access the physical layer control and status registers by the application software. An internal 2K-byte memory is provided that can be configured as multiple variable-size FIFOs and eliminates the need for external FIFOs. Separate FIFOs can be user configured to support general 1394 receive, asynchronous transmit, and isochronous transmit transfer operations. These functions are accomplished by appropriately sizing the general receive FIFO (GRF), asynchronous transmit FIFO (ATF), and isochronous transmit FIFO (ITF). The TSB12LV01B is a revision of the TSB12LV01A, with feature enhancements and corrections. It is pin for pin compatible with the TSB12LV01A with the restrictions noted below. It is also software compatible with the extensions noted below. All errata items to the TSB12LV01A have been fixed, and the following feature enhancements have been made: • Two new internal registers have been added at CFR address 40h and 44h. The Host Bus Control Register at 40h and the Mux Control Register @44h . • Three programmable general-purpose output pins have been added. • Several pin changes have been made.

A 40-60% duty cycle clock is acceptable for host clock frequencies at or below 47 MHz. • The TSB12LV01B does not have bus holder cells on the PHY-link interface. • As a result of removing the bus holder cells, the ISO pin (pin 69) was replaced with a Vcc pin on the TSB12LV01B.
