um_1966b_022 73m1966b demo board user manual rev. 1.2 7 3 connecting the demo board into an existing system t he 73m1966b keychain demo board is designed to be easily connected to an existing system that has access to a pcm and spi interface. table 1 provides the pin and signal names. further detail is provided in the 73m1866b/73m 1966b data sheet . if connectivity between the keychain demo board and the system is prov ided 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 73m1966b demo board to the host board. once connected, the user should check for the integrity of appropriate clock and control sign als. ensure the signals have minimal over - shoot and under - shoot on the signal transitions. consult the 73m1866b/1966b data sheet for informa tion on the signal timing and ensure the host spi conforms to these requirements. the 73m1966b demo board is also designed to plug into the 73m1966b evm motherboard. t his board supports the connection of a pcm test device such as the wandel and goltermann pcm - 4. see the 73m1966b - evm user manual for more information. in order for the 73m1966b demo board to operate correctly it needs to be configured by soft ware. teridian provided reference driver software and linux based command line application ca n be used to configure and control the 73m1966b. contact teridian sales for more information on th e available software. if 73m1966b - db - c has been provided, a cable is included that connects the gui interface j3 to a windows pc with a parallel port. this, alo ng with the gui software, will allow a user to configure the 73m1966b without the need to provide any embedded software. refer to the 73m1966b gui user guide for more information on using the teridian provided gui software. if a 73m1966b motherboard evaluation kit (73m1966b - evm) is being used, the 73m1966b demo board is inserted into the appropriate socket . for further details on operating this system, refer to the 73m19 66b evm user manual . downloaded from: http:///
73m1966b demo board user manual um_1966b_022 8 rev. 1. 2 4 connecting the demo board directly to a pcm test set the 73 m1966b demo motherboard conveniently provides a power connector, a power switch, pcm interface connectors, and clock connectors. however, it is not necessary to utilize the moth erboard when evaluating the device set. in some applications, it might be better to directly connect the 73m1966b demo board to the pcm channel test set. even without the motherboard, the 73m1966b can be used with the gui and a channel test set. if only the 73m1966b demo board is used, the two - row j1 connector has 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 require only the 73m1966b demo board to perform similar tests. figure 2 : connecting the 73m1966b demo board directly to a pcm test set rstb to transmit clock of test set audio to transmit data outpt of tes t set to receive data input of test set j1 digital header 10x2 2 4 6 8 10 12 14 16 18 20 1 3 5 7 9 11 13 15 17 19 sdt to frame sync output of test set vcc3.3 3.3v dc power input intb clko j2 analog header 1 2 3 4 csb vc c3.3 sdi sdo j3 gui header 5x2 2 4 6 8 10 1 3 5 7 9 sdi sdo sclk sclk csb gnd ana ana downloaded from: http:///
