PLL loop filter input
decoupling internal reference voltage output
analog supply voltage
analog ground
high sensitivity IEC input
TTL level IEC input
select IEC input 0 or 1 (0 = IECIN0; 1 = IECIN1); this input has an internal pull-up
resistor
digital audio output for optical and transformer link
digital audio output enable (0 = enabled; 1 = disabled/3-state); this input has an
internal pull-up resistor
enable factory test input (0 = normal application; 1 = scan mode)
enable factory test input (0 = normal application; 1 = observation outputs)
PLL out-of-lock (0 = not locked; 1 = locked); this output can drive an LED
indicates sample frequency = 32 kHz (active LOW); this output can drive an LED
indicates sample frequency = 44.1 kHz (active LOW); this output can drive an LED
indicates sample frequency = 48 kHz (active LOW); this output can drive an LED
use of channel status block (0 = professional use; 1 = consumer use); this output
can drive an LED
digital supply voltage 2
digital ground 2
initialization after power-on, requires only an external capacitor connected to V
DDD
;
this is a Schmitt-trigger input with an internal pull-down resistor
enable power-down input in the standby mode (0 = normal application; 1 = standby
mode)
select microcontroller/stand-alone mode (0 = microcontroller; 1 = stand-alone); this
input has an internal pull-up resistor
microcontroller interface address switch input (0 = 000001; 1 = 000010)
microcontroller interface mode line input
microcontroller interface clock line input
microcontroller interface data line input/output
strobe for control register (active HIGH); this input has an internal pull-down resistor
synchronization for output user data (0 = data available; 1 = no data)
enable factory (scan) test input (0 = normal application; 1 = test clock enable)
copyright status bit (0 = copyright asserted; 1 = no copyright asserted); this output
can drive an LED
validity of audio sample input/output (0 = valid sample; 1 = invalid sample); this pin
has an internal pull-down resistor
pre-emphasis output bit (0 = no pre-emphasis; 1 = pre-emphasis)
audio mute input (0 = permanent mute; 1 = mute on receive error); this pin has an
internal pull-up resistor
