External Clock Input

Mask option allows a user to choose an external clock frequency, as shown in Table 5.1.

Table 5.1 External Clock Frequency and Sampling Frequency

External Clock Frequency

Internal Sampling Frequency

4.096 MHz

4.0 kHz, 5.3 kHz, 6.4 kHz, 8.0 kHz, 10.7 kHz, 12.8 kHz, 16.0 kHz

8.192 MHz

4.0 kHz, 5.3 kHz, 6.4 kHz, 8.0 kHz, 10.7 kHz, 12.8 kHz, 16.0 kHz

16.384 MHz

4.0 kHz, 5.3 kHz, 6.4 kHz, 8.0 kHz, 10.7 kHz, 12.8 kHz, 16.0 kHz

When an external clock frequency were chosen as Mask option and a different frequency input were made, the

sampling frequency changes in proportion to the actual input frequency. For example, while 4.096 MHz external

clock frequency option was selected as Mask option, and when 6.144 MHz external clock is actually input, then

the sampling frequency changes accordingly, e.g. sampling frequency at 1.5 times of those shown in Table 5.1.

Stop Code

The Stop code input (Table 1.1) to the SD pin during playback let the LSI stop playback on the SI’s falling edge

following to the LSB input, and the AOUT fall down to 1/2 V

stops as well.

Timings for the Stop code input are shown below, for 2-pin interfacing in Figure 6.1 and for 3-pin interfacing in

Figure 6.2 respectively.
