(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION
The TSB12LV21B (PCILynx-2) provides a high-performance IEEE 1394-1995 interface with the capability to
transfer data between the 1394 PHY-link interface, the PCI bus interface, and external devices connected to the
local bus interface. The 1394 PHY-link interface provides the connection to the 1394 physical layer device; it is
supported by the onboard 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 Mbit/s, 200 Mbit/s, and 400 Mbit/s.
The link layer 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. The PCILynx-2 complies with
• PCI Local Bus Specification, Revision 2.1
• IEEE Standard for a 1394-1995 High Performance Serial Bus
• IEEE Standard 1212-1991
• IEEE Standard Control and Status Register (CSR) Architecture for Microcomputer Buses
An internal 4 Kbyte memory can be configured as multiple variable-size FIFOs, eliminating the need for external
FIFOs. Separate FIFOs are user configurable to support 1394 receive, asynchronous transmit, and
isosynchronous transmit transfer operations.
