2.6.1 Peripheral Ref Clock

Clock inputs required for peripherals such as XDS110, FT4232, HDMI Transmitter and Audio Codecare generated locally using separate crystals or oscillators. Crystals or Oscillators used to provide the reference clocks to the EVM peripherals are shown in the table below.

Table 2-7 Clock Table
Peripheral Mfr. Part Number Description Frequency
XDS110 Emulator XRCGB16M000FXN01R0 CRY 16.000MHz 8pF SMD 16.000MHz
FT4232 Bridge ECS-120-18-30B-AGN-TR CRY 12.000MHz 18pF SMD 12.000MHz
Audio Codec KC2520Z12.2880C1KX00 OSC 12.288MHz CMOS SMD 12.288MHz
HDMI Transmitter KC2520Z12.2880C1KX00 OSC 12.288MHz CMOS SMD 12.288MHz

The clock required by the HDMI Transmitter can be provided by either the on board oscillator or the SoC’s AUDIO_EXT_REFCLK1, which can be selected through a resistor mux. The EXT_REFCLK1 of the SoC is used to provide clock to the User Expansion Connector on the SKEVM. The 32.768KHz clock to the M.2 module is provided by WKUP_CLKOUT0 of AM62x SIP SoC through a voltage translational buffer.
