For further details concerning filter characteristics when de-emphasis is on, refer to page 13.
— De-emphasis on/off
De-emphasis on: EMP pin = “H”
De-emphasis off: EMP pin = “L”
— Selection of filter coefficient
Soft Mute
Soft muting is performed using the built-in digital attenuator. The attenuation amount of the attenuator circuit is as
follows:
20 log (ATT/256) dB
Although ATT = 0 to 256, when ATT = 0, attenuation sets to –
∞
. If the MUTE pin is set to “H” level, ATT
approaches 0 in single-decreasing increments and the attenuation changes towards –
∞
. On the other hand, when
the MUTE pin is set to the “L” level, ATT approaches 256 in single-increasing increments and the attenuation
amount changes to approach 0. The approximate speed during soft mute is 1024/fs.
Noise Shaper
In order to reduce noise during DF arithmetic output requantization, the first-order noise shaper is utilized.
Double-Rate Support
When the D/N pin is set to “H” level, CD high-speed playback is supported. At this time, BCLK, LRCK and
DATA are input at double the frequency of normal operating times. The system clock operates at 384 fs and with
a clock speed of 512 fs, double-rate is supported. Note that test mode is enabled for clock speeds of 392 fs and
448fs and double-rate is not supported.
Normal-rate mode: D/N pin = “L”
Double-rate mode: D/N pin = “H”
No. 4624-7/14
