Emphasis settings are determined by the state of the DEx_y input pins and configuration registers, as shown in the Output De-
emphasis table below. De-Emphasis is selected as the default power-on mode in following the PCI Express specification, but can be
changed to Pre-emphasis via reprogramming the Loopback and Emphasis Control register using the I2C interface.
Input Level Detect
An input level detect and output squelch function is provided on each channel to eliminate re-transmission of input noise. A con-
tinuous signal level below the Vth- threshold causes the output driver to go to a high-impredance state, so that both the positive and
negative output signal are pulled to VDD by the internal pull-up resistors. This feature supports the L0s PCI Express Electrical Idle
state.
Receiver Detect
Automatic Receiver Detection is a feature that can set the number of active channels. By sensing the presence of a load device on
the output, the channel can be automatically enabled for operation. This allows the PI2EQX5904 to configure itself properly de-
pending on the devices it is communicating with, whether it is a 4-lane, 3-lane, 2-lane or just 1-lane device or adapter card.
Receiver Detect is enabled by the RXD_A, or RXD_B pins, or alternatively via I2C programming. When RXD_A or RXD_B is set
to low, then the Receiver Detect operation for that group of channel is disabled, and those channels go directly to 50-Ohm input
termination to ground and 50-Ohm output termination to VDD (for a valid differential channel input level) or to 2K-Ohm (if the
signal level is less than the threshold level).
