PI2EQX5864C
5.0Gbps 4-Lane PCIe 2.0 ReDdriver
with Equalization, Emphasis and I2C Control
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 PI2EQX5864C to congure 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 I2C programming. When RXD_A or RXD_B is set
to low, the Receiver Detect operation for that group of channels is disabled, and those channels go directly to 50-Ohm input termi-
nation 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).
The RESET# input is used to reset the receiver detect state machine to its initial state. The start of the receiver detect cycle starts
when RESET# transitions from low to high.
When a Receiver Detect cycle begins the differential channel pins are enabled with a 2K-Ohm pull-up to VDD. A 50-Ohm Receiv-
er termination will change the pin level. This pin level is evaluated after a xed time-out, and the channel is then set into the proper
operating state. The register bits RX50_Ax and RX50_Bx represent the receiver detect result for their specic channels.
The I/O operation table summarizes the relationships and operation of receiver detect and other signals involved with I/O control.
