Analog positive supply for clock generator. Nominally +2.5 V.
Analog ground for clock generator PLL.
Digital positive supplies. Nominally +2.5 V.
Digital ground.
Connects to an external filter for the on-chip phase-locked loop.
Connects to an external filter for the on-chip phase-locked loop.
CS493XX clock input. When in internal clock mode (CLKSEL == DGND), this input is
connected to the internal PLL from which all internal clocks are derived. When in external
clock mode (CLKSEL == VD), this input is connected to the DSP clock. INPUT
