DESCRIPTION
Isolation between the CTI and the DTE is an IEEE 802.3 requirement that can be met on signal lines by using a set of pulse transformers. Power isolation for the CTI is achieved using DC-to-DC conversion through a power transformer (see Figure 1, Connection Diagram). The part is functionally the same as the NE83Q92, but with additional features such as a transmit enable input, a carrier detect output and five status LED driver outputs. The NE83Q93 is manufactured on an advanced BiCMOS process and is available in an SOL package making it ideally suited to lap-top personal computers or systems where low power consumption, limited board space and jumperless design is required. Refer to selection flow chart for optimal application.
