Product Description
the most efficient system interconnect switching solution for applications
requiring high throughput, low latency, and simple board layout with a
minimum number of board layers. It provides 192 Gbps of aggregated,
full-duplex switching capacity through 48 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 specification 1.1.

ture. The PCI Express layers consist of SerDes, Physical, Data Link and
Transaction layers. The PES48H12 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
provides full access to the configuration registers in the PES48H12,
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 PES48H12 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.
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 configured. 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.
