New Japan Radio has introduced the NJU26120 DSP that enables sensitive adjustments to sound quality for different TV/audio equipment.

The NJU26120 features New Japan Radio's original eala surround sound, with Dialog Boost, a center-range boosting function and dynamic range compression (DRC), a center-range compression control function. These functions ensure improved voice clarity and stability (achieved by monitoring the sound source and controlling the dynamic range), and a more dialog-nuanced effect free of distracting sound elements.

The device is also equipped with lip-sync delay, ealaBass, 7Band PEQ, tone control, a soft clipper function, headphone surround and a continuous wave detector. The NJU 26120 is well suited for TVs, mini-components, radio cassette players, speaker systems and other TV/audio equipment.

The device is capable of adjusting output time of image and audio with its built-in delay. A maximum delay of 74ms is possible at Fs=48kHz. It's built-in regulator enables operation with 3.3V single power supply. Other key features of the NJU26120 are dialog boost function that enhances dialog clarity by boosting the center range and sound quality adjustment for diverse applications via the 7Band PEQ and tone control.

The 24bit, 61MIP fixed point DSP features an external clock frequency of 12.288MHz, PLL built in and 3.3V operating voltage. The digital audio I/F has three input ports, three output ports. The device also features an I?C bus interface (fast-mode/400Kbps).

Engineering samples are available now in Pb-free SSOP24 packages measuring 6.5mm x 6.4mm x 1.15mm. Sampling price starts at $8.42 per unit.
