TDM MODE APPLICATION
In TDM Mode, several AD1895s can be daisy-chained together
and connected to the serial input port of a SHARC
DSP. The
AD1895 contains a 64-bit parallel load shift register. When the
LRCLK_O pulse arrives, each AD1895 parallel loads its left and
right data into the 64-bit shift register. The input to the shift
register is connected to TDM_IN, while the output is connected
to SDATA_O. By connecting the SDATA_O to the TDM_IN
of the next AD1895, a large shift register is created and is
clocked by SCLK_O.
The number of AD1895s that can be daisy-chained together is
limited by the maximum frequency of SCLK_O, which is about
25 MHz. For example, if the output sample rate, fS, is 48 kHz,
up to eight AD1895s could be connected since 512
× f
S is less
than 25 MHz. In Master/TDM Mode, the number of AD1895s
that can be daisy-chained is fixed to four.
