Digital Sound Processors for FPD TVs

32bit Audio DSP

No.12083EAT04

BU9414FV

●General Description

This LSI is the digital sound processor which made the use digital signal processing for FPD TVs.

DSP of ROHM original is used for the TV sound processor unit, and it excels in cost performance.

There are two digital input systems. An output is a digital output corresponding to 2.1ch.

●Features

■ Digital Signal Processor unit

Word length:

32bit (Data RAM)

The fastest machine cycle:

40.7ns (512fs, fs = 48kHz)

Multiplier:

32 x 24 → 56bit

Adder:

32 + 32 → 32bit

Data RAM:

256 x 32bit

Coefficient RAM:

Sampling frequency:

Master clock :

128 x 24bit

fs = 48kHz

512fs (It is a slave to 256fs of fs = 48kHz, 44.1 kHz, and 32 kHz)

■ Digital signal input (Stereo 2 lines): 16/20/24bit(I2S, Left-Justified, Right-Justified)

Digital signal output (Stereo 2 lines): 16/20/24bit(I2S, Left-Justified, Right-Justified, S/PDIF)

■The sound signal processing function for FPD TVs

Pre-Scaler, DC cut HPF, Channel Mixer, P²Volume(Perfect Pure Volume), BASS, MIDDLE,

TREBLE, Pseudo BASS, Surround, P²Bass, P²Treble, 7Band Parametric EQ,

Master Volume, L/R balance, Post-Scaler, Output signal clipper

(P²Volume, P²Bass, and P²Treble are the sound effect functions of ROHM original.)

●Applications

Flat Panel TVs (LCD, Plasma)
