TL H 9151 – 19
Note 1 0 1% matching may be required to meet the longitudinal balance specification depending on the Longitudinal impedance to ground of the line interface
The 15
and 1k resistors in the line interface circuit should be 1% tolerance and the capacitors should be 10%
Note 2 An alternative circuit which removes the 24
surge-limiting resistors is shown in Figure 10
Note 3 Only necessary in GCI Mode
Note 4 See AN-913 for further information about the line circuit
FIGURE 9 Typical Application in Microwire Mode
TL H 9151 – 20
Note 1 All resistors 1% tolerance and capacitors 10%
Note 2 This circuit provides no surge current limiting for the transformer
Note 3 See AN-913 for further information about the line circuit
