TLH9151 – 19

Note 1

01% matching may be required to meet the longitudinal balance specification depending on the Longitudinal impedance to ground of the line interface

The 15X 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 24X 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

TLH9151 – 20

Note 1

All resistors 1% tolerance and capacitors 10%

Note 2

This circuit provides no surge current limiting for the transformer

Note 3
