CS8420
13.2.1 Pin Description - Hardware Mode 1
Overall Device Control:
DFC0, DFC1 - Data Flow Control Inputs
DFC0 and DFC1 inputs determine the major data flow options available in Hardware mode, as shown in Table 5.
S/AES - Serial Audio or AES3 Input Select
S/AES is connected to ground in Hardware mode 1 in order to select the AES3 input.
MUTE - Mute Output Data Input
If MUTE is low, audio data is passed normally. If MUTE is high, both the AES3 transmitted audio data and the serial
audio output port data is set to digital zero.
OMCK - Output Section Master Clock Input
Output section master clock input. The frequency must be 256x the output sample rate (Fso).
AES3/SPDIF Receiver Interface:
RXP, RXN - Differential Line Receiver Inputs
Differential line receiver inputs, carrying AES3 type data.
RMCK - Input Section Recovered Master Clock Output
Input section recovered master clock output. Will be at a frequency of 256x the input sample rate (Fsi). This is also
a start-up option pin and requires a pull-up or pull-down resistor.
