APPLICATION INFORMATION
CONNECTION DIAGRAMS
Figure 29 shows the basic connection diagram with the necessary power supply bypassing and decoupling components.
It is recommended that the component values shown in Figure 29 be used for all designs.
The use of series resistors (22
to 100
) is recommended for the MCKI, LRCK, BCK, and DATA inputs. The series resistor
combines with the stray PCB and device input capacitance to form a low-pass filter that reduces high-frequency noise
emissions and helps to dampen glitches and ringing present on the clock and data lines.
POWER SUPPLIES AND GROUNDING
The PCM1772 and PCM1773 devices require a 2.4-V typical analog supply for V
CC1
and V
CC2
. These 2.4-V supplies
power the DAC, analog output filter, and other circuits. For best performance, these 2.4-V supplies must be derived from
the analog supply using a linear regulator, as shown in Figure 29.
Figure 29 shows the proper power supply bypassing. The 10-
μ
F capacitors must be tantalum or aluminum electrolytic,
while the 0.1-
μ
F capacitors are ceramic (X7R type is recommended for surface-mount applications).
