Summary
The TCM38C17 is very well suited for line-card applications
and can interface with various different types of SLICs. This
report gives a brief description of how to interface the
TCM38C17 with two different SLICs. It also provides
frequency domain plots to give an estimate of the signal
compared with the noise. The noise floor can be lowered
further with better board design. The noise figures are
greater than would be expected because of a microcontroller
of the TCM38C17 test board. Active components can also
be used in the design of the transhybrid balance to improve
its performance further.
