Applications Information
A combination of the TP3155 TSAC and any CODEC Filter
COMBO from the TP3052 3 4 7 or TP3064 7 series will
result in data timing as shown in Figure 1 Although the FS
output pulse goes high before BCLK goes high the D
put of the combo remains in the TRI-STATE mode until both
are high The eight bit period is shortened to prevent a bus
clash just as it is on the TP3020 1 CODECs

Figure 2 shows typical timing for the control data interface
Figure 3 shows the digital interconnections of a typical line
Alternatively eight full-length bits can be obtained by invert-
ing the BCLK to the combo devices thereby aligning rising
edges of BCLK and FS
