System operating clock generation
♦
Four on-chip PLLs, APLL, MPLL, EPLL & HPLL
♦
APLL is used for ARM Cortex
TM
-A8 and D0_BUS domain (i.e., ARMCLK, HCLKD0, PCLKD0,
HCLKD0_SECSS, and SCLK_ONENAND).
♦
MPLL and EPLL are used for D1_BUS domain (HCLKD1 and PCLKD1) and other peripheral clocks (i.e.,
audio IPs, SPI, and etc.).
♦
HPLL is used for a HD video clock (i.e., SCLK_HDMI).
