1. General Function
This circuit card is used for the Local Node of the IMX-U system. The main function of this circuit card is
to supply basic clock signals to the system. This card receives clock signals from the Phase Lock Oscillator
(PLO) located in TSWM0 of IMG1, distributing the following signals to the Time Division Switch (TSW)
located in TSWM1 of IMG2.
32.768 MHz CLK
