PC1892

MATRIX SURROUND SOUND PROCESSOR

WITH SOUND PROCESSOR

The µPC1892 is a specific IC to reproduce surround sound by using phase shifters and a signal matrix.

µ

PC1892 provides wide sound with two speakers, and rich stereophonic sound with three speakers.

The

µ

In case of stereo signal, the
to emphasize vocal sound (for music), and it has the simulated mode to make monaural signal into wide deep sound. The modes
can be selected freely by using 2-bit parallel control pins.

In addition to this function reproducing surround sound, the
bass and treble control. So it is capable of reducing installation area.

All functions for processing signals of base band sound are provided on one chip.

PC1892 has the movie mode to reproduce sense of immediacy (for movie) and the music mode

µ

PC1892 has a general sound processor that has volume, balance,

FEATURES

• Three surround modes are available: movie, music and simulated

• Built in volume and balance control (All control voltage: 0 V to 5 V)

• Built in tone control (bass, treble) (All control voltage: 0 V to 5 V)

• Built in L+R output for woofer SP

•

µ

PC1892CT-02: The volume and balance attenuation are bigger than µPC1892CT.

Cautions 1. In the case of changing surround mode and power ON/OFF, mute (approx. 200 ms) must be used for pop

noise reduction.

2. Insert resistors between mode select pins (pin 7, 8) and GND, between control pins (pin 16, 17, 18, 19, 20,

23) and GND.

3. Connect a electrolytic capacitor for power supply as close as possible to V

No part of this document may be copied or reproduced in any form or by any means without the prior written
consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this
document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual
property rights of third parties by or arising from use of a device described herein or any other liability arising
from use of such device. No license, either express, implied or otherwise, is granted under any patents,
copyrights or other intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
“Standard“, “Special“, and “Specific“. The Specific quality grade applies only to devices developed based on
a customer designated “quality assurance program“ for a specific application. The recommended applications
of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each
device before using it in a particular application.

Standard: Computers, office equipment, communications equipment, test and measurement equipment,

audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots

Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster

systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)

Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life

support systems or medical equipment for life support, etc.
The quality grade of NEC devices in “Standard“ unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact NEC Sales Representative in advance.
Anti-radioactive design is not implemented in this product.
