The frame rate is equal to the output sampling frequency, f
s
.
The BCKO frequency for the TDM interface is N x 64f
s
, where
N is the number of devices included in the daisy chain. For
Master mode, the output BCKO frequency is fixed to the
reference clock (RCKI) input frequency. The number of

devices that can be daisy-chained in TDM mode is depen-
dent upon the output sampling frequency and the BCKO
frequency, leading to the following numerical relationship:
Number of Daisy-Chained Devices = (f
BCKO
/ f
s
) / 64
Where:
f
BCKO
= Output Port Bit Clock (BCKO), 27.136 MHz maximum
f
s
= Output Port Sampling (or LRCKO) Frequency, 212kHz
maximum.
This relationship holds true for both Slave and Master modes.
Figures 13 and 14 show typical connection schemes for the
TDM mode. Although the TMS320C671x DSP family is
shown as the audio processing engine in these figures, other
TI digital signal processors with a multi-channel buffered
serial port (McBSP
TM
) may also function with this arrange-
ment. Interfacing to processors from other manufacturers is
also possible. Refer to Figure 7 in this data sheet, along with
the equivalent serial port timing diagrams shown in the DSP
data sheet, to determine compatibility.
