Product specification
Digital audio input/output circuit (DAIO)
TDA1315H
Microcontroller based application (receive and/or
transmit)
The microcontroller-based application is illustrated in
Fig.14. Functional blocks are shown for both the receive
and the transmit mode. Here, the IEC signal is input via an
optical fiber link and an associated optocoupler and enters
the TDA1315H at its TTL-level input. The I
2
S-bus output
signal is applied to a digital signal processing module,
which may contain signal processors, DACs, a recording
device etc. An ADC can be an optional source for that
module. As the microcontroller can obtain all status
information and data via the serial bus, it will provide
display information and also will control the whole system,
including the receive/transmit switch. For simplicity
reasons, pin-based mode selection is not shown in this
diagram. In the transmit mode, both system clock and
I
2
S-bus timing are derived from a central timing block. The
IEC output signal feeds an optical fiber link via a suitable
optocoupler.
Concerning the wide supply voltage range of the
TDA1315H, it is not possible to have a
transformer-coupled IEC output that fulfils the “IEC 958”
standard over the full supply voltage range. The output will
have an amplitude of 0.5 V (p-p) with a tolerance of
±
20%.
