3 Connectors
This section describes the 73M1866B Keychain Demo Board connectors. All the digital signals and power supply connections are made through a 20-pin header connector. The audio monitor is also brought out on this connector. Table 2 describes the pins for the J1 connector. For convenience, most digital signals are grouped with the PCM signals 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 can be found on pin 10. There is also a CLKO pin that can be used for the rare case where the 73M1866B is used in the master mode.

17 SDT Serial Data Thru – used in Daisy
18 GND Ground
19 RSTB Reset - low true input 20 GND Ground
Table 2 describes the J2 connector pins. These are the bi-directional PSTN network connections that pass the audio signals to and from the FXO. Table 3: J2 Pin Descriptions Pin Name Function
1 TIP Bidirectional Analog Signaling
2 RING Bidirectional Analog Signaling
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 necessary for the FXO to operate normally. The FXO will not operate if the current drops below approximately 13 mA.

4 Connecting the Keychain Demo Board into an Existing System
The 73M1866B Keychain Demo Board is designed to be easily connected to an existing system that has access to a PCM and SPI interface. Table 2 provides the pin and signal names. Further detail is provided in the 73M1866B/1966B Data Sheet (FDS_1x66B_001). If connectivity between the Keychain Demo Board and the system is provided by ‘blue-wire’, we recommend that 30 AWG wire be used as a minimum and that the maximum length of these wires should not exceed 8 inches (20 cm). It is also recommended that the ground have at least two 30 AWG wires connecting the 73M1866B Keychain Demo Board to the host board. Once connected, the user should check for the integrity of appropriate clock and control signals. Ensure the signals have minimal over- and under-shoot on the signal transitions. Consult the 73M1866B/1966B Data Sheet for information on the signal timing and ensure the host SPI conforms to these requirements. In order for the 73M1866B Keychain Demo Board to operate correctly it needs to be configured by software. Teridian provided Reference Driver Software and Linux based Command Line application can be used to configure and control the 73M1866B. Contact Teridian Sales for more information on the available software.
