Figure 2-6  RCIM II External Interrupt I/O Connector Pin-outs

The external interrupt input signals are 5 volt ttl levels. The external interrupt outputs
(labeled 

EXT_PIG

[0-11]) are driven using a 

74ABT16240

 line driver. The external interrupt

inputs are terminated with 180 ohms to +5 volts, 330 ohms and 0.1 uf to ground. To drive
this input requires a line driver that can sink at least 30 ma. The input termination limits
the speed of the external interrupt signals and helps prevent noise from causing spurious
interrupts. Since most line drivers can sink more current than they can source, the falling
edge of the signal will be faster.

The signals 

EXT_CLKIN

 and 

EXT_CLKOUT 

are used for external 10MHz clocks in or out. An

external clock driving the RCIM II should be capable of driving a 5V ttl signal into a 50
ohm load. The RCIM II will automatically switch to using the external clock if one is
present. The external clock output from the RCIM II is driven using a 

74ABT16240

 line

driver.
