PIN COMPATIBILITY WITH THE ANALOG
DEVICES AD1895 AND AD1896
The SRC4190 is pin-and function-compatible with the AD1895
and AD1896 when observing the guidelines indicated in the
following paragraphs.
Power Supplies.
To ensure compatibility, the VDD_IO and
VDD_CORE supplies of the AD1895 and AD1896 must be
set to +3.3V, while the V
IO
and V
DD
supplies of the SRC4190
must be set to +3.3V.
Pin 1 connection
. For the AD1895, pin 1 is a no connect
(N.C.) pin. For the SRC4190, pin 1 functions as the low group
delay selection input, and should not be left unconnected.
Pin 1 must be connected to either digital ground or the V
IO
supply, dependent upon the desired group delay.
Crystal Oscillator.
The SRC4190 does not have an on-chip
crystal oscillator. An external reference clock is required at
the RCKI input (pin 2).
Reference Clock Frequency.
The reference clock input
frequency for the SRC4190 must be no higher than 30 MHz,
in order to match the master clock frequency specification of
the AD1895 and AD1896. In addition, the SRC4190 does not
support the 768f
S
reference clock rate.
Master Mode Maximum Sampling Frequency.
When the
input or output ports are set to Master mode, the maximum
sampling frequency must be limited to 96kHz in order to
support the AD1895 and AD1896 specification. This is de-
spite the fact that the SRC4190 supports a maximum sam-
pling frequency of 212kHz in Master mode. The user should
consider building an option into his or her design to support
the higher sampling frequency of the SRC4190.
Matched Phase Mode.
Due to the internal architecture of
the SRC4190, it does not require or support the matched
phase mode of the AD1896. Given multiple SRC4190 de-
vices, if all reference clock (RCKI) inputs are driven from the
same clock source, the devices will be phase matched.
