Digital ground 27000 MHz clock input for audio master clock generation. In normal operation this pin must be connected directly to GND. Output to a crystal that is connected to GCLK. If a crystal is not used at GCLK, XO must be left not connected. 27,000 MHz clock or crystal input for main processing clock generation Stand-by input Digital ground Audio master clock input/output. 384, 256, 192 or 128 times the sampling frequency (programmable). Digital power supply (3.3 V) Ground plane of internal PLL circuit PLL configuration input. Allowed to be changed only during RESET. In normal operation both pins must be connected to (digital)GND. PLL capacitor. In normal operation must be connected to PLLGND through a 47nF capacitor. PLL configuration input. Allowed to be changed only during RESET. In normal operation both pins must be connected to (digital)GND. Power supply for internal PLL circuit (3.3 V) In normal operation this pin must be connected directly to VDD. Digital power supply (3.3 V) Reset input Reset, init-pclk, init-display and idle state indication output (Not used) DVD-DSP DVD-DSP start of sector input. Programmable polarity. Digital ground DVD-DSP data valid input. Programmable polarity. DVD-DSP data bit strobe (clock) input. Programmable polarity. DVD-DSP data request output. Programmable polarity.
