11. PIN DESCRIPTIONS
VA—Analog Positive Supply: Pin 34
Analog positive supply for clock generator. Nom2.5 V.
AGND—Analog Supply Ground: Pin 35
Analog ground for clock generator PLL.
VD1, VD2, VD3—Digital Positive Supply: Pins 1, 12, 23
Digital positive supplies. Nom2.5 V.
DGND1, DGND2, DGND3—Digital Supply Ground: Pins 2, 13, 24
Digital ground.
FILT1—Phase-Locked Loop Filter: Pin 33
Connects to an external filter for the on-chip phase-locked loop.
FILT2—Phase Locked Loop Filter: Pin 32
Connects to an external filter for the on-chip phase-locked loop.
CLKIN—Master Clock Input: Pin 30
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
