µPD9903
µPD9903 ANALOG SUBSCRIBER LINE LSI (DIGITAL CODEC)
The µPD9903 is a digital CODEC that can be used in analog subscriber circuits such as private branch exchangers
(PBXs) and switching equipment for central offices. It features three of the functions required for analog subscriber
circuits: 2W/4W conversion, CODEC supervision, and subscriber line supervision.
Use of the µPD9903 in combination with a BS-SLIC (µPC7073) can reduce the number of components required
in analog subscriber circuits.

USE CAUTIONS
(1) Combined characteristics of the µPC9903 and µPD7073
• The µPD9903 is designed to be used in combination with the µPC7073. Therefore, the first half of the electrical
specifications described below are ratings for the µPD9903 as a discrete unit while the second half are
combined ratings with the µPC7073.
• Subscriber circuit constants that are determined by factors such as termination impedance are configured to
enable setting by external order parameters. Consequently, input of an order that is not suitable for the target
impedance may result in failure to obtain the required characteristics.
(2) Absolute maximum ratings
Application of voltage or current in excess of the absolute maximum ratings may result in damage. Be
especially cautious about surges, etc.
(3) Load of by-pass capacitor
Because the µ PC7073 and µ PD9903 use several internal high-frequency operational amplifiers, high power
supply impedance can cause instability in these internal operational amplifiers (such as oscillation). To
suppress such instability and eliminate power supply noise, connect by-pass capacitors (C ACOM = approximate
0.1 µ F) having superior high frequency characteristics as close as possible to the µ PC7073’s power supply
pins (V BB and V CC) and the µ PD9903’s power supply pins (AVDD and DV DD).
(4) Addition of ACOM pin connection capacitor
The voltage of the ACOM pin between the µ PC7073 and µ PD9903 is the reference voltage of the signal
source between the µ PC9903 and µ PC7073. Superposing of noise on this pin may have adverse effects
on transmission characteristics. Therefore, make the wires between the ACOM pins of the two LSIs as short
as possible, and connect capacitors (C ACOM = approximate 0.1 µ F) having superior high frequency
characteristics as close as possible to the pins.

Caution
If the absolute maximum rating for any of the above parameters is exceeded even momentarily,
it may adversely affect the quality of this product. In other words, these absolute maximum
ratings have been set to prevent physical damage to the product. Do not use the product in such
a way as to exceed any of these ratings.

Notes 1. During timing measurement, use 5 ns as the rise time and fall time for the digital input wave form and

2. The µPD9903 is initialized when high level input is applied to the RST pin after applying low level input
for several clock widths. (However, use of the RST pin is not guaranteed during low level input. Also,
low level input alone does not initialize the µPD9903.)

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction
of the gate oxide and ultimately degrade the device operation. Steps must
be taken to stop generation of static electricity as much as possible, and
quickly dissipate it once, when it has occurred. Environmental control must
be adequate. When it is dry, humidifier should be used. It is recommended
to avoid using insulators that easily build static electricity. Semiconductor
devices must be stored and transported in an anti-static container, static
shielding bag or conductive material.
All test and measurement tools
including work bench and floor should be grounded. The operator should
be grounded using wrist strap. Semiconductor devices must not be touched
with bare hands. Similar precautions need to be taken for PW boards with
semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input
level may be generated due to noise, etc., hence causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of
CMOS devices must be fixed high or low by using a pull-up or pull-down
circuitry.
Each unused pin should be connected to VDD or GND with a
resistor, if it is considered to have a possibility of being an output pin. All
handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production
process of MOS does not define the initial operation status of the device.
Immediately after the power source is turned ON, the devices with reset
function have not yet been initialized. Hence, power-on does not guarantee
out-pin levels, I/O settings or contents of registers. Device is not initialized
until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.

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, customers 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 is "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 an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
