2. Introduction
Active Cards
Output Card (EM0409)
The time code output card (EM0409) receives up to 16 inputs from the motherboard. Differential
receivers buffer the inputs and forward them to a 128 inputs x 16 outputs crosspoint array for
switching. The time code outputs are reformatted to comply with SMPTE standards and then sent to
the output backplane through time code signal differential line drivers.
Figure 2-27 shows the time code signal path:
