Introduction
PI2EQX6811ZDE Evaluation Board is designed to allow convenient testing of its operation and features. This board
can work with readily available SATA and eSATA cables for easy connection to SATA3.0 HDD, SSD, OMD storage
components and PC system hosts.
This board allows the PI2EQX6811ZDE device to be powered in +1.5V directly from external power, or 5V with a mini-
USB connector provided to convert.
This User Guide describes the setup, configuration and operation of PI2EQX6811ZDE Eval Board Rev.B. Figure1
provides a top view of PI2EQX6811ZDE Eval Board Rev.B, and Figure2 is bottom view of the board.

SATA and eSATA cables for easy connection to SATA3.0 HDD, SSD, OMD storage components and PC system hosts. This board allows the PI2EQX6811ZDE device to be powered in +1.5V directly from external power, or 5V with a mini- USB connector provided to convert. -
Page 2: Board Operation
PI2EQX6811ZDE is a 1-port (2-channel), bi-directional, signal SATA3.0 re-driver to provide indication when the load is connected to HOST or Device. Figure3 shows the logical block diagram of PI2EQX6811ZDE. Two channels of the PI2EQX6811ZDE are fully independent in operation and configuration by I2C function. Channel configuration of output pre-emphasis, output swing and input equalization must be set appropriately to match the attached cable/trace length and type. -
Page 3: Power Options
Power Options The PI2EQX6811ZDE Evaluation Board provides the options for supplying +1.5V directly or +5V power from mini- USB connector. Figure 4 circles the important connections. 1) Using the +5V power supplied by miniUSB connector (J1). The on-board LDO down-steps the voltage to +1.5V. - Page 4 Open 1) Pin Configurations Configuration begins with I2C_EN# pin with JP23, which must be connected to VDD. The EN pin of the PI2EQX6811ZDE has an internal 200K pull-up resistor to define a high level default (JP20 Open) for normal operation.
- Page 5 2) I2C Configuration On PI2EQX6811ZDE EVB, I2C_EN# pin (JP23) is shorted to GND on EVB, I2C configuration is enabled for all the setting as default. And P8 (JP21, A0) and P9 (JP22, A1) pins are also shorted to GND as default I2C address-C0.

Figure8. Board Connection System Connection The diagrams below show some example system test setups with the PI2EQX6811ZDE Eval Board. Figure9 shows the connection using a NB PC and eSATA Express Card. Note that many notebooks PCs already offer an eSATA port which can be used as the test signal source without the add-in card. -
Page 8: Power-On Sequence
If the host PC and/or HDD are powered on, while the Eval Board is off, there will be no damage to the PI2EQX6811ZDE under typical conditions. If the Eval Board is then powered on, the system will generally detect the SATA HDD as a hot-plug event, and the HDD will begin to operate properly. -
