89HPES12NT3 Data Sheet
Preliminary Information*
Device Overview
The 89HPES12NT3 is a member of the IDT PRECISETM family of PCI Express(R) switching solutions offering the next-generation I/O interconnect standard. The PES12NT3 is a 12-lane, 3-port peripheral chip that performs PCI Express Base switching with a feature set optimized for high performance applications such as servers, storage, and communications/networking. It provides high-performance I/O connectivity and switching functions between a PCIe(R) upstream port, a transparent downstream port, and a non-transparent downstream port. With non-transparent bridging (NTB) functionality, the PES12NT3 can be used standalone or as a chipset with IDT PCIe System Interconnect Switches in multi-host and intelligent I/O applications such as communications, storage, and blade servers where inter-domain communication is required.

management. This includes round robin port arbitration, guaranteeing bandwidth allocation and/or latency for critical traffic classes in applications such as high throughput 10 GbE I/Os, SATA controllers, and Fibre Channel HBAs. Switch Configuration The PES12NT3 is a three port switch that contains 12 PCI Express lanes. Each of the three ports is statically allocated 4 lanes with ports labeled as A, B and C. Port A is the upstream port, port B is the transparent downstream port, and port C is the non-transparent downstream port. During link training, link width is automatically negotiated. Each PES12NT3 port is capable of independently negotiating to a x4, x2 or x1 width. Thus, the PES12NT3 may be used in virtually any three port switch configuration (e.g., {x4, x4, x4}, {x4, x2, x2}, {x4, x2, x1}, etc.). The PES12NT3 supports static lane reversal. For example, lane reversal for upstream port A may be configured by asserting the PCI Express Port A Lane Reverse (PEALREV) input signal or through serial EEPROM or SMBus initialization. Lane reversal for ports B and C may be enabled via a configuration space register, serial EEPROM, or the SMBus.
Product Description Utilizing standard PCI Express interconnect, the PES12NT3 provides the most efficient high-performance I/O connectivity solution for applications requiring high throughput, low latency, and simple board layout with a minimum number of board layers. With support for non-transparent bridging, the PES12NT3, as a standalone switch or as a chipset with IDT PCIe System Interconnect Switches, enables multi-host and intelligent I/O applications requiring inter-domain communication. The PES12NT3 provides 48 Gbps (6 GBps) of aggregated, full-duplex switching capacity through 12 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 1.0a. The PES12NT3 is based on a flexible and efficient layered architecture. The PCI Express layer consists of SerDes, Physical, Data Link and Transaction layers in compliance with PCI Express Base specification Revision 1.0a. The PES12NT3 can operate either as a store and forward or cut-through switch depending on the packet size and is designed to switch memory and I/O transactions. It supports eight Traffic Classes (TCs) and one Virtual Channel (VC) with sophisticated resource

Pin Description
The following tables list the functions of the pins provided on the PES12NT3. Some of the functions listed may be multiplexed onto the same pin. The active polarity of a signal is defined using a suffix. Signals ending with an "N" are defined as being active, or asserted, when at a logic zero (low) level. All other signals (including clocks, buses, and select lines) will be interpreted as being active, or asserted, when at a logic one (high) level.
Signal PEALREV

This value may be overridden by modifying the value of the PALREV bit in the PA_SWCTL register. PCI Express Port A Serial Data Receive. Differential PCI Express receive pairs for port A. PCI Express Port A Serial Data Transmit. Differential PCI Express transmit pairs for port A PCI Express Port B Lane Reverse. When this bit is asserted, the lanes of PCI Express Port B are reversed.

PCI Express Port C Serial Data Transmit. Differential PCI Express transmit pairs for port C PCI Express Reference Clock. Differential reference clock pair input.

Signal CCLKDS
Type I
Name/Description Common Clock Downstream. When the CCLKDS pin is asserted, it indicates that a common clock is being used between the downstream device and the downstream port. Common Clock Upstream. When the CCLKUS pin is asserted, it indicates that a common clock is being used between the upstream device and the upstream port. Master SMBus Slow Mode. The assertion of this pin indicates that the master SMBus should operate at 100 KHz instead of 400 KHz. This value may not be overridden. Non-Transparent Bridge Reset. Assertion of this signal indicates a reset on the external side of the non-transparent bridge. This signal is only used when the switch mode selects a non-transparent mode and has no effect otherwise. Fundamental Reset. Assertion of this signal resets all logic inside the PES12NT3 and initiates a PCI Express fundamental reset. Reset Halt. When this signal is asserted during a PCI Express fundamental reset, the PES12NT3 executes the reset procedure and remains in a reset state with the Master and Slave SMBuses active. This allows software to read and write registers internal to the device before normal device operation begins. The device exits the reset state when the RSTHALT bit is cleared in the PA_SWCTL register by an SMBus master. Switch Mode. These configuration pins determine the PES12NT3 switch operating mode. 0x0 - Reserved 0x1 - Reserved 0x2 - Non-transparent mode 0x3 - Non-transparent mode with serial EEPROM initialization 0x4 - Non-transparent failover mode 0x5 - Non-transparent failover mode with serial EEPROM initialization 0x6 through 0xF - Reserved Table 4 System Pins

Name/Description JTAG Clock. This is an input test clock used to clock the shifting of data into or out of the boundary scan logic or JTAG Controller. JTAG_TCK is independent of the system clock with a nominal 50% duty cycle. JTAG Data Input. This is the serial data input to the boundary scan logic or JTAG Controller.

When no data is being shifted out, this signal is tri-stated. JTAG Mode. The value on this signal controls the test mode select of the boundary scan logic or JTAG Controller. JTAG Reset. This active low signal asynchronously resets the boundary scan logic and JTAG TAP Controller. An external pull-up on the board is recommended to meet the JTAG specification in cases where the tester can access this signal. However, for systems running in functional mode, one of the following should occur: 1) actively drive this signal low with control logic 2) statically drive this signal low with an external pull-down on the board Table 5 Test Pins (Part 2 of 2)

Pin Characteristics
Note: Some input pads of the PES12NT3 do not contain internal pull-ups or pull-downs. Unused inputs should be tied off to appropriate levels. This is especially critical for unused control signal inputs which, if left floating, could adversely affect operation. Also, any input pin left floating can cause a slight increase in power consumption.

The JTAG specification, IEEE 1149.1, recommends that JTAG_TMS should be held at 1 while the signal applied at JTAG_TRST_N changes from 0 to 1. Otherwise, a race may occur if JTAG_TRST_N is deasserted (going from low to high) on a rising edge of JTAG_TCK when JTAG_TMS is low, because the TAP controller might go to either the Run-Test/Idle state or stay in the Test-Logic-Reset state.

Power-Up Sequence
This section describes the sequence in which various voltages must be applied to the part during power-up to ensure proper functionality. For the PES12NT3, the power-up sequence must be as follows: 1. 2. 3. VDDI/O -- 3.3V VDDCore, VDDPE, VDDAPE -- 1.0V VTTPE -- 1.5V
When powering up, each voltage level must ramp and stabilize prior to applying the next voltage in the sequence to ensure internal latch-up issues are avoided. There are no maximum time limitations in ramping to valid power levels. The power-down sequence must be in the reverse order of the power-up sequence.
Power Consumption
Typical power is measured under the following conditions: 25C Ambient, 35% total link usage on all ports, typical voltages defined in Table 14. Maximum power is measured under the following conditions: 70C Ambient, 85% total link usage on all ports, maximum voltages defined in Table 14. All power measurements assume that the part is mounted on a 10 layer printed circuit board with 0 LFM airflow.
