Consumer Interface

In the case of the consumer interface, the standards

call for an unbalanced circuit having a receiver im-

pedance of 75

Ω ± 5%. The connector for the con-

sumer interface is an RCA phono plug (fixed

socket described in Table IV of IEC268-11). The

receiver circuit for the consumer interface is shown

in Figure 23.

TTL/CMOS Levels

The circuit shown in Figure 24 may be used when

external RS422 receivers or TTL/CMOS logic

drive the CS8411/12 receiver section.

Transformers
