9. Clocking Circuits
Two programmable clock circuits are provided on the XM104:
•
•
A Silicon Labs Si570 serial IIC bus re-programmable clock source provides a low-jitter
clock with a user-programmable output frequency from 10 to 810 MHz. The Si570 is
located at IIC address 0x5D. The Si570 clock output (shown in
to a NB6L11 clock driver integrated circuit. One differential output of the NB6L11 clock
driver is AC coupled, with 0.1 uF capacitors, and wired to the FMC HPC connector signal
GBTCLK1_M2C. The second output of the NB6L11 clock driver is connected one of the
Si5368 differential clock inputs. The default clock frequency is 156.25 MHz. Connections to
the FMC HPC connector are defined in
