2Overview
The Texas Instruments XIO2213B is a single-function PCI Express™ (PCIe) to PCI local bus translation
bridge, where the PCI bus interface is internally connected to a 1394b open host controller/link-layer
controller with a 3-port 1394b physical layer (PHY). When the XIO2213B is properly configured, this
solution provides full PCIe and 1394b functionality and performance.
The TI XIO2213B is a PCIe to PCI translation bridge, where the PCI bus interface is internally connected
to a 1394b open host controller/link-layer controller with a 3-port 1394b PHY. The PCIe to PCI translation
bridge is fully compatible with the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. Also, the
bridge supports the standard PCI-to-PCI bridge programming model. The 1394b OHCI controller function
is fully compatible with IEEE Std 1394b and the latest 1394 Open Host Controller Interface (OHCI)
Specification.
The XIO2213B simultaneously supports up to four posted write transactions, four nonposted transactions,
and four completion transactions pending in each direction at any time. Each posted write data queue and
completion data queue can store up to 8K bytes of data. The nonposted data queues can store up to 128
bytes of data.
The PCIe interface supports a ×1 link operating at full 250 Mbit/s packet throughput in each direction
simultaneously. Also, the bridge supports the advanced error reporting capability including ECRC as
defined in the PCI Express Base Specification, Revision 1.1. Supplemental firmware or software is
required to fully utilize both of these features.
Robust pipeline architecture is implemented to minimize system latency. If parity errors are detected,
packet poisoning is supported for both upstream and downstream operations.
SCPS210F –OCTOBER 2008–REVISED MAY 2013
PCIe power management (PM) features include active-state link PM, PME mechanisms, and all
conventional PCI D states. If the active-state link PM is enabled, the link automatically saves power when
idle using the L0s and L1 states. PM active-state NAK, PM PME, and PME-to-ACK messages are
supported. The bridge is compliant with the latest PCI Bus Power Management Specification and provides
several low-power modes, which enable the host power system to further reduce power consumption
Eight general-purpose inputs and outputs (GPIOs), configured through accesses to the PCIe configuration
space, allow for further system control and customization.
Deep FIFOs are provided to buffer 1394 data and accommodate large host bus latencies. The device
provides physical write posting and a highly tuned physical data path for SBP-2 performance. The device
is capable of transferring data between the PCIe bus and the 1394 bus at 100M bit/s, 200M bit/s, 400M
bit/s, and 800M bit/s. The device provides three 1394 ports that have separate cable bias (TPBIAS).
As required by the 1394 Open Host Controller Interface (OHCI) Specification, internal control registers are
memory mapped and nonprefetchable. This configuration header is accessed through configuration cycles
specified by PCIe, and it provides plug-and-play (PnP) compatibility.
The PHY provides the digital and analog transceiver functions needed to implement a 3-port node in a
cable-based 1394 network. Each cable port incorporates two differential line transceivers. The
transceivers include circuitry to monitor the line conditions as needed for determining connection status,
for initialization and arbitration, and for packet reception and transmission. An optional external 2-wire
serial EEPROM interface is provided to load the global unique ID for the 1394 fabric.
The XIO2213B requires an external 98.304-MHz crystal oscillator to generate a reference clock. The
external clock drives an internal phase-locked loop (PLL), which generates the required reference signal.
This reference signal provides the clock signals that control transmission of the outbound encoded
information. The power-down (PD) function, when enabled by asserting the PD terminal high, stops
operation of the PLL. Data bits to be transmitted through the cable ports are latched internally, combined
serially, encoded, and transmitted at 98.304, 196.608, 393.216, 491.52, or 983.04 Mbit/s (referred to as
S100, S200, S400, S400B, or S800 speed, respectively) as the outbound information stream.
To ensure that the XIO2213B conforms to IEEE Std 1394b-2002, the BMODE terminal must be asserted.
The BMODE terminal does not select the cable-interface mode of operation. BMODE selects the internal
PHY-section/LLC-section interface mode of operation and affects the arbitration modes on the cable.
BMODE must be pulled high during normal operation.
Three package terminals are used as inputs to set the default value for three configuration status bits in
the self-ID packet. They can be pulled high through a 1-kΩ resistor or hardwired low as a function of the
equipment design. The PC0, PC1, and PC2 terminals indicate the default power class status for the node
(the need for power from the cable or the ability to supply power to the cable). The contender bit in the
PHY register set indicates that the node is a contender either for the isochronous resource manager (IRM)
or for the bus manager (BM). On the XIO2213B, this bit can only be set by a write to the PHY register set.
If a node is to be a contender for IRM or BM, the node software must set this bit in the PHY register set.

Throughout this data manual, several conventions are used to convey information. These conventions are:
•To identify a binary number or field, a lower-case b follows the numbers. For example, 000b is a 3-bit
binary field.
•To identify a hexadecimal number or field, a lower-case h follows the numbers. For example, 8AFh is a
12-bit hexadecimal field.
•All other numbers that appear in this document that do not have either a b or h following the number
are assumed to be decimal format.
•If the signal or terminal name has a bar above the name (for example, GRST), this indicates the logical
NOT function. When asserted, this signal is a logic low, 0, or 0b.
•Differential signal names end with P, N, +, or – designators. The P or + designators signify the positive
signal associated with the differential pair. The N or – designators signify the negative signal
associated with the differential pair.

to pull the terminal high through a 470-Ω or smaller resistor. This terminal must also
be connected to the LINKON_L input terminal of the LLC section via a 1-kΩ series
resistor. A bus holder is built into this terminal. If the port is to operate in bilingual
mode then the terminal should be tied low via a 1-kΩ resistor and directly connected
to the link's LINKON_L pin with no series termination. After hardware reset, this
terminal is the link-on output, which notifies the LLC section or other power-up logic
to power up and become active. The link-on output is a square-wave signal with a
period of approximately 163 ns (eight PCLK cycles) when active. The link-on output
is otherwise driven low, except during hardware reset when it is high impedance. The
link-on output is activated if the LLC section is inactive (the LPS input inactive or the
LCtrl bit cleared) and when any of the following occurs:
a) The XIO2213B receives a link-on PHY packet addressed to this node.
b) The PEI (port-event interrupt) register bit is 1.
c) Any of the configuration-timeout interrupt (CTOI), cable-power-status interrupt
(CPSI), or state-time-out interrupt (STOI) register bits are 1, and the resuming-port
interrupt enable (RPIE) register bit also is 1.
d) The PHY is power cycled and the power class is 0 through 4.
Once activated, the link-on output is active until the LLC section becomes active
(both the LPS_L input active and the LCtrl bit set). The PHY section also deasserts
the link-on output when a bus reset occurs unless the link-on output is otherwise
active because one of the interrupt bits is set (that is, the link-on output is active due
solely to the reception of a link-on PHY packet). In the case of power cycling, the
LKON signal must stop after 167 ms if the previous conditions have not been met.
Note: If an interrupt condition exists that otherwise causes the link-on output to be
activated if the LLC section were inactive, the link-on output is activated when the
LLC section subsequently becomes inactive.

interface complies with the IEEE Std 1394b-2002 Revision 1.33 beta interface.
When logic low (deasserted), the PHY-section/LLC-section interface complies with
legacy IEEE Std 1394a-2000. This terminal must be pulled high with a 1-kΩ resistor

should be tied to GND. When using the internal regulator, the XIO2213B can
support a maximum of 2-Beta and 1-DS connection simultaneously. If 3-Beta ports
are required to be simultaneously supported, it is recommended to use an external
1.95V regulator.
