■ Difference between YSS903 and YSS915
1. No built-in DAC.
(Refer to the process flow chart in “OPERATIONS”.)
2. Connectable directly with MSB justified data output ADC.
(Refer to “Format 4” of “4. Digital audio interface” in “ PIN FUNCTIONS”.)
3. Microphone interface pins CDI and CDO can be connected on the board.
This feature allows to reduce the number of ports by one.
(Refer to “5. Microcomputer interface” in “ PIN FUNCTIONS”.)
4. Input fader has been added for the microphone echo.
This feature allows to apply fade-in/fade-out control to the microphone echo through designation
with one bit from the microcomputer.
(Refer to “1. Karaoke program” in “ OPERATIONS”, and “3) VCR ($02)” of “1. Functions” in
“REGISTERS”.)
5. Zero level detection function has been added for digital audio output.
YSS915 outputs “0” at the pin “ZERO” when an audio input has been zero for a certain period.
This signal can be used to improve S/N ratio by muting the output of external DAC.
(Refer to “6. Others” in “ PIN FUNCTIONS”.)
6.
An output port PO has been added for controlling peripheral devices.
The port “PO” can be used, as an example, to control the gain of audio output amplifier through this
LSI from the microcomputer.
(Refer to “6. Others” in “ PIN FUNCTIONS”.)
7. A mode with extended band width for microphone echo has been newly added.
Two types of cut-off frequency have been added for the low pass filter.
(Refer to “7) RVR ($06)” and “11) MDR ($1C)” of “1. Functions” in “REGISTERS”.)
8. Internal DSP has been given the operation accuracy of 20 bits.
Internal multiplier-accumulator become 20bit*13bit=24bit therefore overall bit accuracy become
improved from 18bit(YSS903) to 20bit(YSS915).
In through-mode which internal DSP is not used for processing the accuracy of input data is
maintained to output.
