PCI Power Management Event occurred PCIe Interface The Tsi382 evaluation board implements a single lane PCIe Interface. It is designed to connect to a PCIe system with a standard x1 finger connector. The system must provide the REFCLK and PERSTN signals.
PCIe 3.3V supply 3.3V_A_384 Passive Filter The target power draw of the Tsi382 is a maximum of 1W, all supplies combined. The supplies to the Tsi382 are controlled during ramp up using enable pins on regulators and switches. 1.4.2.1 PCIe The PCIe CEM Specification 1.1 defines power limits on PCIe slots according to the number of lanes...

The evaluation board senses the presence of this supply, and disables the slave PCIe slot power. For the case of a separate external ATX supply, all four slots are provided with the required power. Tsi382 (LQFP) Evaluation Board User Manual Integrated Device Technology 602020_MA001_02...
1. Board Design 1.4.3 Power Sequencing On power-up, the board’s power sequence is as follows: 1. 1.2V powered on 2. PCI I/O slot power and pull-ups, and Tsi382 3.3V 12V/-12V/5V PCI are not sequence controlled. 1.4.4 System Power Design Figure 2 illustrates the power distribution for the riser card.
PCI Vaux (PCI Auxiliary) Support PCI connectors are provided with a 3.3V supply to the vaux pins only during operation. There is no support for this power supply in standby mode. This feature is not documented in the Tsi382 evaluation board schematic.
Other Interfaces 1.6.1 JTAG Interface To support debug and testing of device, JTAG access to the Tsi382 is available using a standard JTAG header for Wiggler connection. For more information about accessing the Tsi382 using JTAG, see the JTAG Register Access Software Application Note.

Switches S3 and S4 are used to set the PCI bus external clock frequency. By default the PCI bus clock source is the Tsi382. The external clock can only be connected to the PCI bus by replacing resistors on the board. When an external clock source is used, an on-board PLL is used to set the proper bus clock frequency.

2.1.2 Push Button SW1 is used to turn the ATX power supply ON. This switch is used only when the Tsi382 evaluation board is powered up with a stand-alone ATX power supply. SW2 is used to reset the evaluation board. When pushing the reset button, the board is reset the same way a PCIe system reset would reset the board.
2. Configurable Options Shunt Jumpers Shunt jumpers control special features on the evaluation board (see Figure 7). These jumpers are explained in the following sub-sections.
