BALANCED TRANSMISSION TERMINATING APPARATUS AND RECEIVER USING IT

摘要

PROBLEM TO BE SOLVED: To provide a balanced transmission terminating apparatus in which saturation of a common mode choke coil can be suppressed while preventing damage. SOLUTION: Impedances of a common mode choke coil 23, an impedance element R1, and an impedance element R2 are set such that a common mode current Ic2 flowing into the common mode choke coil 23 does not exceed a rated current Ir. An undue common mode current Ic2 can be prevented from flowing into the common mode choke coil 23 and saturation and damage of the common mode choke coil 23 can be suppressed.
