TCA-232
4. Application
The TCA-232 is used to couple two DCE devices
together whose clocks are of the same frequency
but are not “in phase.”
An example is an extension of a multiplexor
channel using modems in a “tail circuit” (see
Figure 4-1
). When the distance between the two
tail modems is significant, there is a difference in
phase between the multiplexor’s transmit clock
and the adjacent modem’s receive clock, resulting
in transmission errors. The TCA-232 acts as a buffer
between the DCEs to prevent these transmission
errors.
