1.2.3. Transmitter PLL

In Cyclone® V GX/GT/SX/ST devices, there are two transmitter PLL sources: CMU PLL (channel PLL) and fPLL. The channel PLL can be used as CMU PLL to clock the transceivers or as clock data recovery (CDR) PLL.

Note: Cyclone® V transceiver channels support full-duplex operation. The CMU PLL is sourced from the channel PLL of channels 1 or 4.
