ATT DATA
Audio output level = 20 log ———————
[dB]
100H
For example, the formula below calculates the time required for the attenuation level to increase from 00H to EEH
when a 4STEP UP command is executed. Note that the control microprocessor must provide enough of a time margin
for this operation to complete before issuing the next attenuation level set command.
238 levels
× 4 steps
———————— =21.6 ms
44.1 kHz (LRSY)
Note: * Setting the attenuation level to values of EFH or higher is disallowed to prevent overflows in one-bit D/A converter calculations from causing noise.
Mute output; Pin 46: MUTEL, pin 55: MUTER
These pins output a high level when the attenuator coefficient is set to 00H and the data in each channel has been zero
for a certain period. If data input occurs once again, these pins go low immediately.
18. Digital filter outputs; Pin 33: LRCKO, pin 34: DFORO, pin 35: DFOLO, pin 36: DACKO
Data for use with an external D/A converter is output MSB first from DFORO and DFOLO in synchronization with
the falling edge of DACKO. These pins are provided so that an external D/A converter can be used if desired.
Although this output is from 8x oversampling filters for normal-speed playback, digital 4
× oversampling filters are
used in double-speed playback.
