1 Introduction
The 73M1966B Demo Board can be used with the 73M1966/1866 Demo Motherboard or in tar get
app l ications where it is connected either by the appropr i ate connector or “blue wired” into the system that
is will be used with. The active circuitry is identical to the 73M1866B Keychain Board other than including
a connector for the GUI interface cable. The GU I cab le is includ ed in the 73M19 66B Evaluation Kit and
the Demo Board kit if it has been sp ecifically ordered.
1.1 Package Contents

• PCM Connectivi ty Application Note
1.2 Safety an d ES D Notes
Connecting live voltages to the 73M1966 Demo Board system will result in p otential l y hazard ous voltages
on the boards.
Extreme caution should be taken when handling the 73M1966B Demo Board after
connection to live voltages!
The 73M1966B Demo Board is ESD sensitive! ESD precautions should be t ak en wh en
handling this board!

This section describes the 73M1966B Demo Board connectors. All the digital signals and power supply
conn ections are made thr ough a 20-pin header connector. The audi o monit or i s also brought ou t on this
connector . Table 1 describes the pins for th e J1 connect or . For convenience, most digital signals are
grouped wit h the PCM si g nals on the odd pins from pin 1 to pin 7, and the PCM CLKI pin is on pin 8. The
SPI signals can be found on the odd pins 9 through 17. Reset is on pin 19. The interrupt output is on pin
16. There are two power pins on pins 2 and 4 and two ground pins on pins 18 and 20. The audio monitor
output ca n be found on pin 10. There is also a C LKO pin that can be used for the rare case where the
73M1866B is used in the master mode.

2 TIP Bidi r ectional Analog Signaling
3 RING Bidirect ional Analog Signaling
4 N/C No Connect
The signals on the TIP and RING pins should also have a DC current that would normally come from the
PSTN. This current will usually be in the range of 20 to 100 mA, but typically about 40 mA. This current
is n ecessary for the F XO t o operate norm ally. The FXO will not operate if the current drops b elow
approximately 13 mA.
Table 5 describes the J3 connector pins. J3 is use d to co nnect a host P C to the Dem o Board to provide
GUI control.

3 Connecting the Demo Board into an Existing System
The 73M 1966B Keychain Demo Board is desi gned to be easily connected to an existing system that has
access to a PCM and SPI in terface. Table 1 provides the pin and signal names. Further detail i s
provided in the 73M1866B/73M1966B Data Sheet. If con nect i vity betwe en the Keychain D emo Board
and the system is pr ovided by ‘blue-wire’, we recommend that 30 AWG wire be used as a minimum and
that the maximum l ength of these wires should not exceed 8 inch es (20 cm). It i s also recom men ded that
the ground have at least two 30 AWG wires connecting the 73M1966B Demo Board to the host board.
Once connected , the user should ch eck for the integrity of ap prop r i ate clock and control si gnal s. Ensure
the signal s have m i nimal over-shoot and und er -shoot on the signal transitions. Consult the
73M1866B /1966B Data Sheet for information on the sig nal timing and ensu r e the host SPI conform s to
these requirements.
The 73M1966B Demo Board is also designed t o pl ug in to the 73M1966B EVM Moth er board . This board
supports the con nect i on of a PCM test device such as the Wandel and Goltermann PC M -4. See the
73M1966B-EVM User M an ual for more information.
In or der for the 73M1966B Dem o Board to operate co r rectly it n eeds t o be configured by soft ware.
Teridian provided Reference Driver Software and Linux based Command Line application can be used to
configure and contr ol the 73M 1966B. Contact Teridi an Sales for more in formation on the available
software.
If 73M1966B-DB-C has been p r ovided, a cable is includ ed that connects the GUI Interface J3 to a
Windows PC wit h a parallel por t. Thi s, along with the GUI software, will allow a user to configure the
73 M1 966B wit hout the n eed to provide any embed ded software. Refer t o the 73M1966B GUI User Guide
for more informati on on using the Terid i an pr ovided GUI softwar e.
If a 73M1966B Motherboard Evaluation Kit (73M1966B-EVM) is b eing used, the 73M 1966B Dem o Board
is inserted in to the app r opriat e socket . For further details on operating this sy stem, r efer to the
73M1966B EVM User Manual.

4 Connecting the Demo Board Directly to a PCM Test Set
The 73M1966B Demo Motherboard co nveniently p r ovides a po wer connector, a power sw itch, P C M
interface conn ectors, and clock co nnectors. However, it is not n ecessary t o util ize the Motherboard when
evalu ating the device set . In some applica tions, it might be b etter to direct ly connect the 73 M1 966B
Demo Board to th e PC M channel test set. Even without the Motherboard, the 73M1966B can be used
with the G U I and a ch annel test set.
If onl y t he 73M1966B Dem o Board is used, the two-row J1 co nnector h as all the necessary signals to
connect to the digital signals of the channel test set and 3.3 V power as shown in Figure 2. Other PCM
highway test sets should also requir e only the 73M1966B Demo Board to perform similar tests.
