C-13-1250-F-SLC(2)
Signal Detect (LVTTL output)
The C-13-1250(A)C-F-SLC(2) transceivers are equipped with LVTTL signal detect output. The standard LVTTL output eliminates the
need for a LVPECL to LVTTL level shifter in most applications.

Power Coupling
A suggested layout for power and ground connections is given in figure 3A below. Connections are made via separate voltage and
ground planes. The mounting posts are at case ground and should not be connected to circuit ground. The mounting posts are at case ground
and should not be connected to circuit ground. The ferrite bead should provide a real impedance of 50 to 100 ohms at 100 to 1000 MHz. By-
pass capacitors should be placed as close to the 10-pin connector as possible.
