Version
• Added step 5 "If you reconfigure PLL for data rate change you must recalibrate the PLL" in
Embedded Reconfiguration Streamer block of ATX PLL.
• Added "The CLKUSR pin must be assigned a 100-125 MHz clock. For used transceiver TX and RX
channels, do not assert the analog reset signals indefinitely" in "Unused/Idle Clock Line
Requirements" section.
• Added a sentence in fPLL/CMU PLL "For protocol jitter compliance at datarate > 10 Gbps, Intel
recommends using the dedicated reference clock pin in the same triplet with the fPLL/CMU PLL as
the input reference clock source."
