APPLICATIONS INFORMATION
This section provides practical applications information for
hardware and systems engineers who will be designing
the SRC4194 into their end equipment.
TYPICAL CONNECTIONS
Figure 10 and Figure 11 illustrate typical connection
diagrams for Hardware and Software modes, respectively.
In Hardware mode, dedicated pins are controlled using
external logic circuitry, hardwiring pins high or low, or by
using the general-purpose I/O pins of a microprocessor or
DSP. In Software mode, the SRC4194 is controlled via the
4-wire SPI port and optional GPIO from either a
microprocessor or DSP.
Figure 12 illustrates the power-supply options for the
SRC4194. When utilizing +3.3V for the core supply, the
REGEN input (pin 26) must be driven high in order to
enable the on-chip linear voltage regulator. The VDD33
pins are supplied with +3.3V and the VDD18 pins are left
unconnected.
When utilizing +1.8V for the core supply, the REGEN input
(pin 26) must be driven low in order to disable the on-chip
linear voltage regulator. The VDD18 pins are supplied with
+1.8V and the VDD33 pins are left unconnected.
Recommended power-supply bypass capacitor values
are shown in Figure 10 through Figure 12. Ceramic
capacitors (X7R chip type) are recommended for the
0.1
μ
F capacitors, while the 10
μ
F capacitors may be
tantalum or multi-layer X7R ceramic chip type, or
through-hole or surface-mount aluminum electrolytic
capacitors.
