WebFor each serial transceiver channel, there is a ring PLL called Channel PLL (CPLL). The GTH in the 7 series FPGA has an additional shared PLL per quad, Quad PLL (QPLL). This QPLL is shared LC PLL to support high speed, high performance, and low power multi-lane applications. Figure 1-1 shows a Quad in a 7 series device. Web(Xilinx GTX, GTH, GTY type transceivers with their CPLLs and QPLLs or Intel ATX PLL, FPLL, CDR PLL, ... For example GTX QPLL actually have two none overlapping frequency bands with a hole in the middle. GTH and GTY do have two QPLLs with slightly different VCO min/max. ...
