Input Clock
32K Clock: It is also called “sleep clock” and is mainly used for system timing and sleeping.
19.2 MHz System Clock: It is mainly used to provide the input clock for APLL and DPLL.
Output Clock
There is one output clock: MCLK. MCLK provides 16 MHz clock to audio codec.

SPI
OMAP5912 has one SPI, which has four chip selects for connecting four external SPI components. The
available SPI signals are SPI.DOUT, SPI.DIN, SPI.CLK and SPI.CS. The system uses SPIF.CS2 to
select the IF processor AD9864, to configure the register of AD9864. The connection of SPI is shown
below.
