Figure 4. CPC5601 Application Circuit Using the LITELINK III and the LITELINK Snoop Circuit

¹This design was tested and found to comply with FCC part 68 with this part.

Other compliance requirements may require a different part.

²Higher noise power supplies may require substitution of a 220

H inductor,

Toko 380HB-2215 or similar. See the power quality section of Clare applica-

tion note AN-146, Guidelines for Effective LITELINK Designs for more informa-

tion. Both application circuits use the same components for setting AC

termination and the telephone line current limit.
