Clock Synthesizers
The Zynq Ult MPSoC (ZU11/17/19EG) Carrier board supports two 10-output Clock Synthesizer
“SI5341B
-D-
GM”
for on board clock
distribution. This Clock Generator outputs are connected to PS-GTR, PL-GTH and PL-GTY Transceiver Banks Reference Clock on Board to
Board Connectors through 0.01uF AC coupling capacitors. An external 48MHz crystal is connected to this Clock Synthesizer
for reference.
This Clock Synthesizer
supports from 100 Hz to 1028 MHz clock output and configurable through PS I2C0.
