LRCLK Routing Switches
2-8
SCLKOUT1 of TAS3103
–
U1 serves as the SCLK for the ADCs and
SCLKOUT2 of TAS3103
–
U1 serves as the SCLK for the 6-channel DAC and
the SPDIF Tx. Both SCLKOUT clocks are routed to a multiplexer. Switch S11
selects whether SCLKOUT1 of TAS3103
–
U1 (S11 set to L) or SCLKOUT2 of
TAS3103
–
U1 (S11 set to H) is routed to pin SCLKIN of TAS3103
–
U2. This
multiplexer is necessary as either clock can be the higher frequency clock in
certain applications and SCLKIN must be provided the higher of the two
clocks.
If TAS3103
–
U1 is the master and provides SCLK to an external device on the
I
2
S input port, switch S9 must be set to L to enable the gate driving SCLK to
the external device. When the TAS3103 is a master, the signal on pin SCLKIN
is not used, and thus the state of the signal into the pin is not an issue.

LRCLK Routing Switches
Figure 2
–
5 illustrates the LRCLK options provided by the EVM. There are
three choices for sourcing LRCLK
SPDIF Rx, I
2
S input header, and
TAS3103
–
U1. Again, if the SPDIF Rx is used to source LRCLK, it must also
source MCLK and SCLK.
S3 selects between the SPDIF Rx LRCLK (S3 = H) and an I
2
S input port
LRCLK (S3 = L). If the I
2
S input port is used to source LRCLK, S9 must be set
to H to place in a 3-state condition the driver used to supply LRCLK to an input
device connected to the I
2
S input port. (Note that S3 and S9 served the same
functions for SCLK).
The output of the S3 selection is routed to a buffer whose output is controlled
by switch S7. In the TAS3103, LRCLK is a bidirectional pin. When the TAS3103
is serving as clock master, any devices driving this pin must be placed in a
3-state condition. When S7 is set to H, the driver is placed in the 3-state
condition.
