2.5.1 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. Crystals or Oscillators used to provide the reference clocks to the EVM peripherals are shown in below table.

Table 2-3 Clock Table
Peripheral Mfr. Part # Description Frequency
XDS110 emulator (Y3) XRCGB16M000FXN01R0 CRY 16.000MHz 8 pF SMD 16.000 MHz
FT4232 Bridge (Y4) 445I23D12M00000 CRY 12.000MHz 18 pF SMD 12.000 MHz
M.2 Interface (U45) ECS-327MVATX-2-CN-TR OSC 32.768KHz CMOS SMD 32.768 KHz
Audio Codec (U98) LMK6CE012288CDLFT OSC 12.288MHz CMOS SMD 12.288 MHz
HDMI Framer (U23) LMK6CE012288CDLFT OSC 12.288MHz CMOS SMD 12.288 MHz

The clock required by the HDMI Transmitter can be provided by either the on-board oscillator or the AUDIO_EXT_REFCLK1 of the SOC, 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 SK EVM. The 32.768 KHz clock to the M.2 module is provided by default from WKUP_CLKOUT0 ball of AM62P SOC.
