2.6.1 Peripheral Ref Clock

Clock inputs required for peripherals such as XDS110, FT4232, M.2 Interface, HDMI Framer and Audio Codec are generated locally using separate crystals or oscillators. Table 2-6 shows the crystals or oscillators used to provide the reference clocks to the EVM peripherals.

Table 2-6 Clock Table
PeripheralMfr. Part #DescriptionFrequency
XDS110 emulator (Y3)XRCGB16M000FXN01R0CRY 16.000MHz 8pF SMD16.000MHz
FT4232 Bridge (Y4)445I23D12M00000CRY 12.000MHz 18pF SMD12.000MHz
M.2 Interface (U45)ECS-327MVATX-2-CN-TROSC 32.768KHz CMOS SMD32.768KHz
Audio Codec (U98)LMK6CE012288CDLFTOSC 12.288MHz CMOS SMD12.288MHz
HDMI Framer (U23)LMK6CE012288CDLFTOSC 12.288MHz CMOS SMD12.288MHz

The clock required by the HDMI Transmitter can be provided by either the onboard oscillator or the AUDIO_EXT_REFCLK1 of the SoC, which can be selected through a resistor multiplexer. The EXT_REFCLK1 of the SoC is used to provide clock to the User Expansion Connector on the SK EVM. The 32.768KHz clock to the M.2 module is provided by default from WKUP_CLKOUT0 ball of AM62P SoC.
