Filter characteristics
The overall filter characteristic of the UDA1321 in flat mode is given in Fig.8. The overall filter characteristic of the
UDA1321 includes the filter characteristics of the DSP in flat mode plus the filter characteristic of the FSDAC
(f
s
= 44.1 kHz).
DSP extension port
An external DSP can be used for adding extra sound processing features via the digital I/O-bus. The UDA1321 supports
the standard I
2
S-bus data protocol and the LSB-justified serial data input format with word lengths of 16, 18 and 20 bits.
Using the 4-pins digital I/O-bus the UDA1321 device acts as a master, controlling the BCK and WS signals. The period
of the WS signal is determined by the number of samples in the 1 ms frame of the USB. This implies that the WS signal
does not have a constant period time, but is jittery. Using the 6-pins digital I/O-bus GP2, GP3 and GP4 are the output
pins (master) and GP0, GP1 and GP5 are the input pins (slave).
For characteristic timing of the I
2
S-bus input interface see Figs 9 and 10.
