3.1 Clock Distribution
The DM388 module contains the following reference clocks:
• Y1 – 32.768-kHz real-time clock (RTC) to the power management IC (TPS6591133)
• Y2 – 20-MHz crystal for the device oscillator inputs
• Y3 – 27-MHz crystal for the auxiliary oscillator inputs
• U5 – 32.768-KHz oscillator for the reference clock
The slow clock to the WLAN WiLink WL1837 module is provided by CLKOUT1 from the processor or by
CLK32OUT from the PMIC. The default clock is from PMIC.
Figure 3-1 shows the board-clock distribution circuit.

3.2 Reset Circuit and Distribution
Power good from PMIC TPS6591133 (nRESPWRO2), power good from DDR power IC (DDR_PGOOD),
and reset from the CSK carrier card are monitored to generate the power-on reset (PORn) to the DM388
processor. A 3-input AND gate is used to implement the reset logic. Warm reset for the processor is the
input from the CSK carrier card through the board-to-board connector.
The reset to the parallel camera module and the externally connected Ethernet are reset from the DM388
processor through the board-to-board connectors.
Figure 3-2 shows the board-reset circuit and distribution.
