The
data are edge aligned. Introducing a phase shift of –180° to sampling clock (c0)
ensures that the input data is center-aligned with respect to the c0, as shown in

The Stratix IV device family contains up to eight left and right PLLs with up to four
PLLs located on the left side and four on the right side of the device. The left PLLs can
support high-speed differential I/O banks on the left side; the right PLLs can support
high-speed differential I/O banks on the right side of the device. The high-speed
differential I/O receiver and transmitter channels use these left and right PLLs to
generate the parallel clocks (rx_outclock and tx_outclock) and high-speed clocks
(diffioclk).

right PLLs for Stratix IV E, GT, and GX devices. The PLL VCO operates at the clock
frequency of the data rate. Clock switchover and dynamic reconfiguration are allowed
using the left and right PLL in high-speed differential I/O support mode.
