No. Pin Name I/O Pin Function
1 CDOUT O
Data out (SPI) In SPI mode, CDOUT is the output data from the control port interface on the
CS8420.
2 CS
−
Control Port Chip Select (SPI) A falling edge on this pin puts the CS8420 into SPI control port
mode. In SPI mode, CS is used to enable the control port interface on the CS8420.
3 EMPH O
Pre-emphasis Indicator Output
4 RXP I
Differential Line Receiver Inputs, carrying AES3-type data.
5 RXN I
Differential Line Receiver Inputs, carrying AES3-type data.
6 VA+
−
Positive supply for the analog section. Nom5.0 V.
7 AGND
−
Ground for the analog section.
8 FILT
−
PLL Loop Filter
9 RST I Reset Input
10 RMCK O
Input section recovered master clock output.
Will be at a frequency of 128x or 256x the input sample rate (Fsi).
11 RERR
−
Receiver Error Indicator
12 ILRCK I/O
Serial Audio Input Port, Left/Right Clock input or output Word rate clock for the audio data on
the SDIN pin. The frequency will be at the input sample rate (Fsi)
13 ISCLK I Serial bit clock input or output for audio data on the SDIN pin.
14 SDIN I Audio data serial input pin.
15 TCBL I/O Transmit Channel Status Block Start
16 OSCLK I/O
Serial Audio Output Port, Bit Clock input or output
17 OLRCK I/O
Serial Audio Output Port, Left/Right Clock input or output Word rate clock for the audio data on
the SDOUT pin. The frequency will be at the output sample rate (Fso)
18 SDOUT O
Audio data serial output
19 INT O
Interrupt Output
20 U
−
User Data The U pin may optionally be used to input User data for transmission by the AES3
transmitter. Alternatively, the U pin may be set to output User data from the AES3 receiver.
21 OMCK I
Output section master clock input.
The frequency must be 256x, 384x, or 512x the output sample rate (Fso).
22 DGND
−
Ground for the digital section.
23 VD+
−
Positive supply for the digital section. Nom5.0 V.
24 H/S

25 TXN O Differential Line driver outputs
26 TXP O
Differential Line driver outputs
27 CDIN I
Serial Control data in (SPI)
In SPI mode, CDIN is the input data line for the control port interface
28 CCLK I/O
Control Port clock
