Chapter 1 Description of the EB16T7 Eval Board ® Introduction Notes The 89HPES16T7 switch (also referred to as PES16T7 in this manual) is a member of the IDT PCI Express® standard (PCIe®) based line of products. It is a 16-lane, 7-port switch, with 4 serial lanes on three ports and 1 serial lane on four ports.
IDT Description of the EB16T7 Eval Board Revision History Notes October 19, 2006: Initial publication of board manual. November 13, 2006: In Tables 2.7 and 2.8, changed MSMSDDR to MSMBADDR and removed refer- ences to P23MERGEN, P45MERGEN, and SWMODE[3]. March 30, 2007: In Figure 1.1, revised diagram to show a x4 connection from the PES16T7 device to the x4 downstream slot.

Chapter 2 Installation of the EB16T7 Eval Board ® EB16T7 Installation Notes This chapter discusses the steps required to configure and install the EB16T7 evaluation board. All available DIP switches and jumper configurations are explained in detail. The primary installation steps are: 1.
IDT Installation of the EB16T7 Eval Board Notes Figure 2.1 SuperMicro X6DH8-G2 Motherboard Reference Clocks The PES16T7 requires two differential reference clocks. The EB16T7 derives both of these clocks from a common source which is user-selectable. The common source can be either the host system’s reference clock or the onboard clock generator.
IDT Installation of the EB16T7 Eval Board Notes The source for the onboard clock is the ICS557-03 clock generator device (U8) connected to a 25MHz oscillator (Y1). When using the onboard clock generator, the EB16T7 allows selection between multiple clock rates and spread spectrum settings via DIP switches as described in Tables 2.2 and 2.3 respectively. Spread Spectrum technology reduces peak EMI emissions by modulating the frequency to spread the peak energy over a wider bandwidth.
IDT Installation of the EB16T7 Eval Board Notes Signal +12V Table 2.5 External Power Connector - J1 PCI Express Serial Data Transmit Termination Voltage Converter A DC-DC converter (U6) provides a 1.5V PCI Express serial data transmit termination voltage (shown as VTTPE or VPETVTT) to the PES16T7.
IDT Installation of the EB16T7 Eval Board Fundamental Reset Notes There are two types of Fundamental Resets which may occur on the EB16T7 evaluation board: – Cold Reset: During initial power-on, the onboard voltage monitor (TLC7733D) will assert the PCI Express Reset (PERSTN) input pin of the PES16T7.
IDT Installation of the EB16T7 Eval Board Notes Signal Description CCLKDS Common Clock Downstream. The assertion of this pin indicates that all downstream ports are using the same clock source as that provided to downstream devices. This pin is used as the initial value of the Slot Clock Configuration bit in all of the Link Status Registers for downstream ports.

IDT Installation of the EB16T7 Eval Board SMBus Master Interface Notes Connected to the master SMBus interface are four 16-bit I/O Expanders (PCA9555) and a serial EEPROM (24LC512). Four I/O Expanders are used as the interface for the onboard hot-plug controllers (MIC2591B).

IDT Installation of the EB16T7 Eval Board Notes Note: These x16 PCI Express connectors comply with the PCIe specification. However, the downstream ports on the EB16T7 are electronically connected in either a x4 configuration (port 6) or a x1 configuration (ports 2, 3, 4 and 5). According to the PCI Express specification, the PRSNT1# pin should be wired to the farthest available PRSNT2# pin on the connector.
Chapter 3 Software for the EB16T7 Eval Board ® Introduction Notes This chapter discusses some of the main features of the available software to give users a better under- standing of what can be achieved with the EB16T7 evaluation board using the device management soft- ware.
