Description

Sampling Rate Converter

Unit (SCU)

(For All Products)

Overall

specification

• Includes ten SRC modules

— Supports the quality suitable for audio sound (High-sound-

quality type) (THD+N -132dB): six modules

— Supports the quality suitable for voice sound (general-sound-

quality type) (THD+N -96dB): four modules

• The SRC module is capable of correcting phase change and delay

(timing jitter) generated during data transfer over external

memories or external devices.

• The channel count conversion unit (CTU), mixer (MIX), and digital

mute and volume function (DVC) can be used on two fixed output

channels.

Sampling rate

conversion

(SRC)

• Capable of asynchronous sampling rate conversion

• Supports resolutions up to 24 bits

• Two kinds of filter type for SRC.

— Supports the quality suitable for audio sound (High-sound-

quality type) (THD+N -132dB): Realized the filter by passband

-1dB@0.4575FS, cutoff -18dB@0.5FS.

— Supports the quality suitable for voice sound (general-sound-

quality type) (THD+N -96dB): Realized the filter by passband -

1dB@0.4561FS, cutoff -72dB@0.5FS. (Characteristics of each

filter is written in the equivalent/up-sampling cases.)

• Automatically generates antialiasing filter coefficients

• For monaural to eight-channel sound sources

Sampling Rate Converter

Unit (SCU)

(For All Products)

Channel count

conversion

unit (CTU)

• Downmixing and splitter functions

— Conversion of eight input channels into four output channels

— Conversion of six input channels into two output channels

— Conversion of two input channels into four sets of two output

channels

— Conversion of one input channel into eight sets of one output

channel

— No conversion

Mixer (MIX)

• Mixing (adds) two to four sources into one

• Ratio for adding sources is selectable

• Ratio is dynamically changeable

• Mixing with volume ramp is available (ramp period is selectable)

Digital volume

and mute

function (DVC)

• Volume control function including digital volume, volume ramp,

and zero-crossing mute

• The digital volume function is specified by a 24-bit fixed-point

value within the range from 0 to 8 times (mute, or -120 to 18 dB)

• The volume ramp function can be used for soft mute, fade-in,

fade-out, or desired volume adjustment

• The volume ramp period can be changed within the sampling

range from the 0th to 23rd power of 2

• The zero-crossing mute function silences the sound at the zero-

crossing point of the audio data
