1
E029 PLL loop filter input
2
E029 decoupling internal reference voltage output
3
E008 analog supply voltage
4
E004 analog ground
5
E007 high sensitivity IEC input
IECIN0
6
IPP04 TTL level IEC input
IECSEL
7
IUP04 select IEC input 0 or 1 (0 = IECIN0; 1 = IECIN1); this input has an internal pull-up
resistor
IECO
8 OPFH3 digital audio output for optical and transformer link
IECOEN
9
IUP04 digital audio output enable (0 = enabled; 1 = disabled/3-state); this input has an
internal pull-up resistor
TESTB
10 IPP04 enable factory test input (0 = normal application; 1 = scan mode)
TESTC
11 IPP04 enable factory test input (0 = normal application; 1 = observation outputs)
UNLOCK
12 OPP41A PLL out-of-lock (0 = not locked; 1 = locked); this output can drive an LED
FS32
13 OPP41A indicates sample frequency = 32 kHz (active LOW); this output can drive an LED

25 IOF24 microcontroller interface data line input/output
STROBE
26 IDP04 strobe for control register (active HIGH); this input has an internal pull-down resistor
UDAVAIL
27 OPF23 synchronization for output user data (0 = data available; 1 = no data)
TESTA
28 IPP04 enable factory (scan) test input (0 = normal application; 1 = test clock enable)
COPY
29 OPP41A copyright status bit (0 = copyright asserted; 1 = no copyright asserted); this output
can drive an LED
INVALID
30 IOD24 validity of audio sample input/output (0 = valid sample; 1 = invalid sample); this pin
has an internal pull-down resistor
DEEM
31 OPF23 pre-emphasis output bit (0 = no pre-emphasis; 1 = pre-emphasis)
MUTE
32 IUP04 audio mute input (0 = permanent mute; 1 = mute on receive error); this pin has an
internal pull-up resistor
