AES3/SPDIF Input (Input) - Differential receiver inputs carrying AES3 or S/PDIF encoded digital
data. RXP[1:0] comprise the non-inverting inputs of the differential input multiplexer; and RXN[1:0]
comprise the inverting inputs of the input multiplexer. Unused inputs should be tied to AGND.
Analog Power (Input) - Analog power supply, nominally +3.3 V. Care should be taken to ensure that
this supply is as noise-free as possible, as noise on this pin will directly affect the jitter performance of
the recovered clock.
Analog Ground (Input) - Ground for the analog circuitry in the chip. AGND and DGND should be
connected to a common ground area under the chip.
Serial Audio Output Format Select (Input) - Used to select the serial audio output format after RST
is released. See
Master/Slave Select (Input) - Used to select Master or Slave settings for the output serial audio ports
after RST is released. See
Non-Validity Receiver Error/Receiver Error (Output) - Receiver error indicator. NVERR is output by
default, RERR is selected by a 20 k resistor to VL.
Validity Data/AUDIO (Output) - If a 20 k pull-down is present on this pin, it will output serial Validity
data from the AES3 receiver, clocked by the rising and falling edges of OLRCK2 in master mode. If a
20 k pull-up is present, the pin will be low when valid linear PCM data is present at the AES3 input.
Crystal/Oscillator In (Input) - Crystal or digital clock input for Master clock. See
on page
Crystal Out (Output) - Crystal output for Master clock. See
