CLOCK AND RESET SIGNALS | ||||
GRST# | A15 | A15 | I PU | Global power reset. This reset brings all of the TUSB73x0 internal registers to their default states. When GRST# is asserted, the device is completely nonfunctional. GRST# should be asserted until all power rails are valid at the device. If a 24 MHz or 48 MHz reference clock is used instead of a crystal, GRST# must remain asserted until the 24 MHz or 48 MHz clock is stable. |
XI | A23 | A23 | I | Crystal input. This terminal is the crystal input for the internal oscillator. The input may alternately be driven by the output of an external oscillator. When using a crystal a 2-MΩ feedback resistor is required between XI and XO. |
XO | A22 | A22 | O | Crystal output. This terminal is crystal output for the internal oscillator. If XI is driven by an external oscillator this pin may be left unconnected. When using a crystal a 2-MΩ feedback resistor is required between XI and XO. |
FREQSEL | B14 | B14 | I | Frequency select. This terminal indicates the oscillator input frequency and is used to configure the correct PLL multiplier. This pin should be set low for normal operation. |
PCIE_REFCLKP | A45 | A45 | I | PCI Express Reference Clock. PCIE_REFCLKP and PCIE_REFCLKN comprise the differential input pair for the 100-MHz system reference clock. |
PCIE_REFCLKN | B41 | B41 | I | |
PERST# | A40 | A40 | I | PCI Express Reset Input. The PERST# signal is used to signal when the system power is stable. The PERST# signal is also used to generate an internal power on reset |
