Output Swing Control
Output De-emphasis Adjustment
Input Level Detect
An input level detect and output squelch function is provided on each channel to eliminate re-transmission of
input noise. A continuous signal level below the V
dance state, so that both the positive and negative output signal are pulled to V
tors. 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 PI2EQX5804C to confi g-
ure itself properly depending 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 I
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 V
input level) or to 2K-Ohm (if the signal level is less than the threshold level).
Emphasis settings are determined by the state of the DEx_y input pins and confi guration 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 specifi cation, but can be changed to Pre-emphasis via reprogramming the Loopback and Empha-
sis Control register using the I
