The configuration for jumper W5 specifies whether a board is to drive the onboard 10-MHz
oscillator onto the RTSI bus, receive the RTSI bus clock, or disconnect from the RTSI bus clock.
This clock source, whether local or RTSI signal, is then divided by 10 and used as the Am9513A
frequency source.
The jumper selections are listed in Table 2-9.
Table 2-9. Configurations for RTSI Bus Clock Selection
Configuration W5
Disconnect board from RTSI bus clock; use local
oscillator C - D, E - F (factory setting)
Receive RTSI bus clock signal A - B, E - F
Drive RTSI bus clock signal with local oscillator A - B, C - D
Figures 2-21, 2-22, and 2-23 show the jumper positions for each of the configurations described
above.
