On-Board PLL
PLL Connections
The PLL contains six output pins, one of which is left unconnected. The other five are labelled SYS_CLK1 through SYS_CLK5. SYS_CLK4 connects to JP3 and SYS_CLK5 connects to JP2. The other three pins are connected directly to the FPGA. The table below illustrates the PLL connections.
| PLL PIN | CLOCK NAME | CONNECTION |
|---|---|---|
| LCLK1 | SYS_CLK1 | FPGA – N14 (Bank 14, MRCC) |
| LCLK2 | SYS_CLK2 | FPGA – F4 (Bank 35, SRCC) |
| LCLK3 | SYS_CLK3 | FPGA – F5 (Bank 35, MRCC) |
| LCLK4 | SYS_CLK4 | JP3 – Pin 48 |
| CLK5 | SYS_CLK5 | JP2 – Pin 3 |
| CLK6 | Not Connected |
