Do not connect loads lower than 300 Ohms.
5.7. Clock Input and Output on SMA connectors
There are five SMA connectors at the top of the case, on the right side. They are al
dedicated to clock inputs or clock outputs.
The MCLKI clock input is one of the three clock source for the I2S
input interface.
The MCLKI clock output is a buffered output of the clock actually used
by the IS input interface.
The MCLKO clock input is one of the three clock source for the I2S
output interface.
The MCLKO clock output is a buffered output of the clock actually
used by the IS output interface.
The Framer clock input is one of the two clock source for the Framer
operation.
All inputs are 100 Ohms terminated. The voltage level at the 100
Ohms load must be comprised between 2V5 and 3V6.
5.8. SLIMbus connector
The SLIMbus connector is a DIL6 male pin header (pitch spacing
2,54mm / 0,1”). It is located at the top of the case, in the lower left
corner.
The pin assignment is as follow:
1 - SLIMbus Clock
2 - SLIMbus Data
3 - 3V3 power supply (do not connect if not needed)
4 - GND (supply ground)
5 - GND (supply ground)
6 - GND (supply ground)
