Table 4-1 Clock and Reset Signals
PIN TYPE DESCRIPTION
NAME TUSB7320 TUSB7340
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
