Line-Interface Hybrids Work With ISDN And ISDL

The APC13119 is a quad module that contains four complete interface circuits with everything needed to use an Infineon PEB24902 chip in either line card or terminal applications. This includes transformer isolation, common-mode noise suppression, echo cancellation, and over-current and multiple stages of over-voltage protection. The device is aimed at high-density applications where its 58 x 55 x 12.5 mm dimensions save up to 50% of the pc board area required for a discrete component implementation.
