2.6 Clocking

Figure 2-5 shows the clock architecture of the AM62P SK EVM.

SK-AM62P-LP Clock Architecture Figure 2-5 Clock Architecture

A clock buffer of part number LMK1C1103PWR is used to drive the 25MHz clock to the SoC and the two Ethernet PHYs. LMK1C1103PWR is a 1:3 LVCMOS clock buffer, which takes the 25MHz crystal/LVCMOS reference input and provides three 25MHz LVCMOS clock outputs. The source for the clock buffer shall be either the CLKOUT0 pin from the SoC or a 25MHz oscillator, the selection of which is made using a set of resistors. By default, an oscillator is used as an input to the clock buffer on the AM62P SK EVM. Outputs Y1 and Y2 of the clock buffer are used as reference clock inputs for the two Gigabit Ethernet PHYs.

There is one external crystal (32.768KHz) attached to the AM62P SoC to provide clock to the WKUP domain.
