Product Description
Utilizing standard PCI Express interconnect, the PES22H16 provides
the most efficient I/O connectivity for applications requiring high
throughput, low latency, and simple board layout with a minimum
number of board layers. It provides 88 Gbps of aggregated, full-duplex
switching capacity through 22 integrated serial lanes, using proven and
robust IDT technology. Each lane provides 2.5 Gbps of bandwidth in
both directions and is fully compliant with PCI Express Base specifica-
tion 1.1.
The PES22H16 is based on a flexible and efficient layered architec-
ture. The PCI Express layer consists of SerDes, Physical, Data Link and
Transaction layers. The PES22H16 can operate either as a store and
forward switch or a cut-through switch and is designed to switch memory
and I/O transactions. It supports eight Traffic Classes (TCs) and two
Virtual Channels (VCs) with sophisticated resource management to
enable efficient switching and I/O connectivity.
SMBus Interface
The PES22H16 contains two SMBus interfaces. The slave interface
provides full access to the configuration registers in the PES22H16,
allowing every configuration register in the device to be read or written
by an external agent. The master interface allows the default configura-
tion register values of the PES22H16 to be overridden following a reset
with values programmed in an external serial EEPROM. The master
interface is also used by an external Hot-Plug I/O expander.
Six pins make up each of the two SMBus interfaces. These pins
consist of an SMBus clock pin, an SMBus data pin, and 4 SMBus
address pins. In the slave interface, these address pins allow the
SMBus address to which the device responds to be configured. In the
master interface, these address pins allow the SMBus address of the
serial configuration EEPROM from which data is loaded to be config-
ured. The SMBus address is set up on negation of PERSTN by
sampling the corresponding address pins. When the pins are sampled,
the resulting address is assigned as shown in Table 1.
As shown in Figure 3, the master and slave SMBuses may be used
in a unified or split configuration. In the unified configuration, shown in
Figure 3(a), the master and slave SMBuses are tied together and the
PES22H16 acts both as a SMBus master as well as a SMBus slave on
this bus. This requires that the SMBus master or processor that has
access to PES22H16 registers supports SMBus arbitration. In some
systems, this SMBus master interface may be implemented using
general purpose I/O pins on a processor or micro controller, and may
not support SMBus arbitration. To support these systems, the
PES22H16 may be configured to operate in a split configuration as
shown in Figure 3(b).
In the split configuration, the master and slave SMBuses operate as
two independent buses and thus multi-master arbitration is never
required. The PES22H16 supports reading and writing of the serial
EEPROM on the master SMBus via the slave SMBus, allowing in
system programming of the serial EEPROM.
