CPC5622-EVAL-600R, LITELINK III Evaluation Board based on CPC5622A and CPC5712U Voltage Monitor

Beschreibung

• CPC5622-EVAL-600R, Evaluation Board ships with the CPC5622A LITELINK III and CPC5712U Voltage Monitor to demonstrate the functionality of a PSTN terminating two-wire interface that provides both the analog voice transmission and signaling functions. The analog interface is configured to provide a 600-Ohm resistive AC impedance with 0dB gain in both the transmit and receive directions. While the CPC5622A provides the hook-switch and ringing detect signaling functions, the CPC5712U is utilized to monitor and detect changes in the DC line voltage to determine loop status and signaling information sent by the network
