ADAU1590
must be placed very close to the respective pins with direct
connection. This is important for reliable and safe operation
of the device. One additional 1 μF capacitor in parallel to the
100 nF capacitor is also recommended. A bulk bypass capacitor
of 470 μF is also recommended to remove the low frequency
ripple due to load current.
Similarly, one 100 nF capacitor is recommended between each
DVDD/DGND and AVDD/AGND. These capacitors also must
be placed close to their respective pins with direct connection.
CLOCK
The ADAU1590 uses 24.576 MHz for the master clock, which is
512 × f
S
(
f
S
= 48 kHz). There are several options for providing
the clock.
Option 1: Using a Quartz Crystal
A quartz crystal of 24.576 MHz frequency can be connected
between the XTI and XTO pins using two load capacitors
suitable for the crystal oscillation mode.
Option 2: Using a Ceramic Resonator
The ADAU1590 can also be used with ceramic resonators
similar to crystal by using the XTI and XTO pins.

Option 3: Using an External Clock
The ADAU1590 can be provided with an external clock of
24.576 MHz at the XTI pin. The logic level for the clock input
should be in the range of 3.3 V and 50% typical duty cycle.
For systems using multiple ADAU1590s, it is recommended to
use only one clock source if the ADAU1590s share the same
power supply to prevent the beat frequencies of asynchronous
clocks from appearing in the audio band.
Multiple ADAU1590s can be connected in a daisy chain by
providing or generating a master clock from one ADAU1590
and subsequently connecting its XTO output to the XTI input
of the next ADAU1590, and so on. However, using a simple
logic buffer between the XTO pin of one ADA1590 to the XTI
pin of the next ADAU1590 is recommended. Because the clock
output is now buffered, it can be connected to the XTI inputs of
the remaining ADAU1590s, depending on the fanout capability
of the logic buffer used.
