11.APPENDIX D: EXTERNAL AES3-S/PDIF-IEC60958 RECEIVER
11.1 AES3 Receiver External Components
COMPONENTS
Coax
The CS42516 AES3 receiver is designed to accept only consumer-standard interfaces. The standards call
for an unbalanced circuit having a receiver impedance of 75 Ω ±5%. The connector is an RCA phono socket.
The receiver circuit is shown in
plexer using the consumer interface.
In the configuration of systems, it is important to avoid ground loops and DC current flowing down the shield
of the cable that could result when boxes with different ground potentials are connected. Generally, it is
good practice to ground the shield to the chassis of the transmitting unit and connect the shield through a
capacitor to chassis ground at the receiver. However, in some cases, it is advantageous to have the ground
of two boxes held at the same potential and make the electrical connection through the cable shield. Gen-
erally, it may be a good idea to provide the option of grounding or capacitively coupling the shield to the
chassis.
When more than one RXP pin is driven simultaneously, as shown in
crosstalk between inputs. To minimize this crosstalk, provide as much trace separation as is reasonable and
choose non-adjacent inputs when possible.
The circuit shown in
TTL/CMOS logic outputs drive the CS42516 receiver input.
