Preliminary specification
Universal Serial Bus (USB) Audio
Playback Recording Peripheral (APRP)
UDA1335H
DSP extension port
An external DSP can be used for adding extra sound processing features via the digital I/O-bus. The UDA1335H 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-pin digital I/O-bus the UDA1335H 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 time period, but is jittery. Using the 6-pin digital I/O-pins GP2, GP3 and GP4 are
output pins (master) and GP0, GP1 and GP5 are input pins (slave).
The characteristic timing of the I
2
S-bus input interface is illustrated in Figs 8 and 9.
