Output Confi guration
The PI2EQX5864C provides fl exible output strength and emphasis controls to provide the optimum signal to pre-compensate for
losses across long trace or noisy environments so that the receiver gets a clean with good eye opening. Control of output confi gura-
tion is grouped for the A and B channels, so that each channel within the group has the same setting.
Output confi guration can be set via I
settings for output level control, as specifi ed by the SELx_y registers.
Output Swing Control
Emphasis settings are determined by the state of the Dx_y input pins and confi guration registers, as shown 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 repro-
gramming the Loopback and Emphasis Control register using the I
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 continu-
ous signal level below the V
tive output signal are pulled to V
